Erklärung 오답률 in your Level:

At the A1 level, '오답률' might be a bit too advanced for your daily conversation, but it's great to understand the parts it's made of. '오' means 'wrong,' and '답' means 'answer.' When you take a small quiz in your Korean class, your teacher might show you which questions many students got wrong. While a beginner would usually just say '틀렸어요' (It's wrong), knowing that '오답' means a 'wrong answer' is a very helpful building block. Think of it like this: '정답' is a 'right answer' (O), and '오답' is a 'wrong answer' (X). You can start by recognizing these two words on your test papers. Don't worry about the 'rate' (률) part yet; just focus on the fact that '오답' is the opposite of '정답.' In a classroom, if a teacher points to a question and says '오답,' they are telling you the answer provided was not correct. It is a very formal way of saying 'wrong answer.' Even at A1, you can use '오답' to label your mistakes in your notebook. This helps you organize your study habits early on. For example, you can have a section called '오답' where you write down the sentences you got wrong during practice. This is the first step toward understanding the more complex '오답률' later.

At the A2 level, you can start using the full word '오답률.' You are now learning how to describe things using percentages and rates. '오답률' means the 'percentage of wrong answers.' You will hear this word if you attend a Korean language school or if you are looking at your results for a mock TOPIK (Test of Proficiency in Korean) exam. At this level, you should be able to say whether the '오답률' was 'high' (높아요) or 'low' (낮아요). For example, if a grammar point like '-니까' is very difficult, many students will get it wrong, and the teacher might say '이 문제는 오답률이 높아요' (The error rate for this question is high). You can also use it to set goals for yourself. You might say, '이번에는 오답률을 낮추고 싶어요' (I want to lower the error rate this time). This shows you are moving beyond simple sentences and starting to talk about your learning process statistically. It's also important to notice the spelling: it's '오답률,' not '오답율.' This is a common rule you learn at this level—using '률' after a consonant. Practice saying it slowly: O-dap-ryul. Even though the 'ㄹ' sound is there, in fast speech it might sound like 'O-dam-nyul.' Understanding this will help your listening skills significantly.

At the B1 level, you are expected to understand '오답률' in broader contexts, such as news reports or academic discussions. You are no longer just looking at your own test scores; you are looking at data. For instance, you might read an article about the CSAT (Suneung) that discusses the '오답률 Top 10.' This means the ten questions that the most students got wrong. At this level, you should be able to use '오답률' with more complex verbs. Instead of just saying it is 'high' or 'low,' you can say '오답률을 분석하다' (to analyze the error rate) or '오답률이 집계되다' (the error rate is being tallied). You should also be able to compare '오답률' with '정답률' (correct answer rate). For example, '정답률이 20%라는 것은 오답률이 80%라는 뜻입니다' (A correct answer rate of 20% means the incorrect answer rate is 80%). This shows a logical understanding of the term. You might also encounter this word in a professional setting, such as a company meeting where training results are discussed. Being able to use this word correctly in a report or a presentation will make your Korean sound much more professional and precise. You are now using the word as a tool for evaluation and planning.

At the B2 level, '오답률' becomes a key term for analyzing trends and societal issues. You might participate in a debate about the Korean education system and use '오답률' to argue that certain exams are too difficult. For example, you could say, '오답률이 95%에 달하는 킬러 문항은 학생들에게 과도한 스트레스를 줍니다' (Killer questions with an error rate reaching 95% give students excessive stress). At this stage, you should be comfortable with the Hanja roots and how they relate to other words like '오류' (error), '오해' (misunderstanding), and '비율' (ratio/rate). You can also discuss the '오답률 분포' (distribution of error rates) among different demographics, such as students in Seoul versus students in rural areas. This level of usage shows that you can handle abstract statistical concepts in Korean. You might also use the word in the context of Big Data or AI, discussing how algorithms use '오답률' to provide personalized feedback. Your ability to use '오답률' in these varied and complex scenarios indicates a strong grasp of intermediate-high vocabulary. You are not just using the word; you are using it to build complex arguments and analyze data.

At the C1 level, your understanding of '오답률' should be nuanced and deeply integrated into your professional or academic discourse. You can use the term to critique assessment methodologies. For instance, you might argue that a high '오답률' doesn't necessarily mean a question is 'good' or 'discriminatory' (변별력이 있다), but rather that it might be poorly phrased or ambiguous. You are able to use sophisticated collocations like '오답률을 상회하다' (to exceed the error rate) or '오답률의 추이를 지켜보다' (to observe the trend of the error rate). You can also write detailed reports analyzing the '오답률' in a linguistic corpus, identifying which grammatical structures are most difficult for L2 learners. Your pronunciation should be natural, including the nasalization [오담뉼], and your spelling should be flawless. At this level, you might even use the term metaphorically in a business strategy context to talk about the 'failure rate' of certain market predictions, though '오답률' remains primarily tied to 'answers' and 'evaluations.' You should be able to read complex charts and graphs in Korean news or academic journals where '오답률' is a primary axis of data.

At the C2 level, you have a near-native mastery of '오답률' and can use it in highly specialized fields like psychometrics or educational statistics. You can discuss 'item response theory' (문항 반응 이론) and how '오답률' is used to calculate the 'difficulty parameter' of a test item. You are aware of the subtle differences between '오답률' and similar terms like '부적합률' (non-conformity rate) or '오류 발생률' (error occurrence rate) in technical manuals. You can engage in high-level academic research, perhaps writing a thesis on the 'Correlation between Reading Comprehension Strategies and the Incorrect Answer Rate in Abstract Texts.' You understand the cultural weight of the word in Korea—how a single '오답률' statistic can trigger a national conversation about education reform or the fairness of the national exam. Your usage is indistinguishable from a highly educated native speaker, whether you are giving a keynote speech, writing a formal policy proposal, or engaging in a sophisticated intellectual debate. You can also play with the word in creative writing, using it to symbolize the failures and trials of a character's journey in a metaphorical 'test of life.'

오답률 in 30 Sekunden

오답률 means the 'incorrect answer rate.' It is used to measure the difficulty of test questions.
It is a compound of '오답' (wrong answer) and '률' (rate). It is always spelled with '률' after '답'.
A high error rate indicates a difficult question, often called a 'killer question' in Korea.
It is a key metric in the Korean education system, especially for the Suneung (CSAT).

The Korean word 오답률 (O-dap-ryul) is a compound noun essential for anyone navigating the academic or professional landscape in South Korea. It literally translates to 'wrong answer rate' or 'incorrect answer percentage.' In a culture where education and standardized testing, particularly the Suneung (CSAT), hold immense weight, this term is used daily by students, teachers, and data analysts to determine the difficulty level of specific questions or entire examinations. When you hear the word 오답률, you are looking at the statistical inverse of the success rate. If a question has an 오답률 of 80%, it means that 80% of the test-takers failed to select the correct option, marking it as a 'killer question' (킬러 문항) in Korean parlance.

Academic Context: Teachers use this metric to identify which concepts students are struggling with most. For example, if the 오답률 for a geometry question is unexpectedly high, the teacher might dedicate an entire lesson to re-explaining that specific theorem.
Statistical Context: In surveys or psychological testing, researchers analyze the 오답률 of trap questions to measure the reliability of the participants' responses or the clarity of the survey design.

The word is composed of three Hanja characters: O (誤 - error), Dap (答 - answer), and Ryul (率 - rate). Understanding this breakdown helps learners recognize the word in various forms. For instance, '정답률' (Jeong-dap-ryul) is the opposite, meaning the correct answer rate. The nuances of using 오답률 often revolve around intensity; a 'high' (높은) 오답률 signifies a very difficult task, while a 'low' (낮은) 오답률 suggests the material was mastered by most. It is not just about numbers; it is about the story those numbers tell regarding the difficulty of the material and the preparedness of the learners.

이번 수학 시험에서 15번 문항의 오답률이 가장 높았습니다. (The incorrect answer rate for question number 15 was the highest in this math exam.)

Furthermore, the term extends beyond the classroom into corporate training and online certifications. Companies tracking employee performance on safety quizzes or compliance tests will generate reports focusing on the 오답률 to mitigate risks. If the 오답률 on a 'fire safety' section is high, it indicates a critical need for better training materials. Thus, the word is inherently linked to the concept of 'improvement through analysis.' By looking at where people fail, organizations and individuals can focus their resources on the most problematic areas.

오답률을 줄이기 위해서는 오답 노트를 작성하는 것이 중요합니다. (To reduce the incorrect answer rate, it is important to keep a wrong-answer notebook.)

In social settings, students might discuss their 'personal 오답률' jokingly to express how poorly they think they did on a test. '내 오답률은 아마 100%일 거야' (My wrong answer rate will probably be 100%) is a common hyperbolic expression of exam anxiety. This versatility—from formal statistical reporting to casual student slang—makes it a vital word for intermediate learners to master.

Using 오답률 correctly requires pairing it with the right verbs and adjectives. Most commonly, it is paired with '높다' (high) and '낮다' (low). Because it is a statistical noun, it often appears as the subject of a sentence describing a state or the object of a sentence describing an action to change that state (like reducing it).

Subject Marker (-이/가): 오답률이 예상보다 높아서 놀랐어요. (I was surprised because the incorrect answer rate was higher than expected.)
Object Marker (-을/를): 우리는 다음 시험에서 오답률을 낮추기 위해 노력해야 합니다. (We must work to lower the incorrect answer rate in the next exam.)

When discussing specific questions, the particle '의' (possessive) or the construction '에 대한' (regarding/for) is used. For instance, '3번 문항의 오답률' (Question 3's error rate) or '이 문제에 대한 오답률' (The error rate for this problem). In academic papers or news articles, you will see it combined with '집계되다' (to be counted/tallied) or '분석하다' (to analyze).

전문가들은 이번 불수능의 주요 원인으로 국어 영역의 높은 오답률을 꼽았습니다. (Experts pointed to the high incorrect answer rate in the Korean language section as the main cause of this 'Fire Suneung' [extremely difficult exam].)

In more advanced contexts, you might see '오답률' used in comparative structures. 'A 유형의 오답률이 B 유형보다 월등히 높다' (The error rate for Type A is significantly higher than Type B). This demonstrates how the word functions as a tool for comparison and evaluation. It is also common to see it in the context of '오답률 분포' (distribution of incorrect answer rates), which refers to how errors are spread across different groups of students.

인공지능을 활용해 학생들의 오답률 패턴을 분석하고 있습니다. (We are analyzing students' incorrect answer rate patterns using AI.)

When writing about it, ensure you use the correct spelling. A common mistake is writing '오답율' (o-dap-yul). According to Korean spelling rules, '률' is used after a consonant (except ㄴ), while '율' is used after a vowel or the consonant ㄴ. Since '답' ends in the consonant 'ㅂ', '률' is the correct form. Mastering this small orthographic detail will make your writing look much more professional and native-like.

The word 오답률 is ubiquitous in South Korean society, primarily due to the nation's intense focus on education. The most common place you will hear this word is on the evening news following major national exams. News anchors will report on the '오답률 Top 5' questions, interviewing star teachers (known as 'Il-ta' instructors) who explain why those specific questions were so difficult for the students. These broadcasts are watched by millions of anxious parents and students alike.

In Hagwons (Private Academies): Teachers at Hagwons frequently use this term when handing back mock exams. They might say, '이 문제는 오답률이 90%가 넘어요. 다들 집중해서 들으세요.' (The error rate for this problem is over 90%. Everyone, listen closely.)
On YouTube and Educational Apps: Korean educational YouTubers often title their videos '오답률 높은 문제 풀이' (Solving problems with high error rates) to attract students looking for help with the toughest material.

Another common setting is in university lectures, especially in statistics, psychology, or education departments. Professors discuss '오답률' as a variable in research. For instance, a psychology professor might discuss how stress levels correlate with the '오답률' in cognitive tasks. In this context, the word takes on a more clinical and data-driven tone compared to the high-pressure environment of the Suneung.

EBS 방송에서 어제 시험의 오답률 통계를 발표했습니다. (EBS broadcasted the incorrect answer rate statistics for yesterday's exam.)

You will also find this word in the business world, specifically in Human Resources and corporate training. When employees take mandatory training courses on topics like data privacy or workplace harassment, the HR department analyzes the '오답률' to see if the training was effective or if the questions were poorly phrased. If a specific question has a high '오답률', it often leads to a revision of the training module itself. Therefore, even after graduating, Koreans continue to encounter this word in their professional lives.

Finally, in the age of Big Data, '오답률' is a key metric for AI-driven learning platforms like Riiid or Santa TOEIC. These apps use the '오답률' of thousands of users to predict which questions a specific user is likely to get wrong, creating a personalized learning path. In these tech-heavy environments, '오답률' is a data point that drives algorithm-based education.

The most frequent mistake learners make with 오답률 is a spelling error rooted in a complex Korean phonology rule. Many people mistakenly write it as '오답율'. In Korean, the suffix for 'rate' can be either '-율' (-yul) or '-률' (-ryul). The rule states that you use '-율' if the preceding syllable ends in a vowel or the consonant 'ㄴ'. In all other cases—meaning after any other consonant—you must use '-률'. Since '답' ends in 'ㅂ', the only correct spelling is '오답률'. This is a common pitfall even for native speakers, so mastering it will set you apart.

Spelling Rule Example: Correct: 오답률 (ends in ㅂ), 성공률 (ends in ㅇ). Correct: 비율 (ends in vowel), 생존율 (ends in ㄴ).

Another mistake is confusing '오답률' with '오답'. '오답' simply means 'wrong answer' (a single instance), while '오답률' is the 'rate' or 'percentage' (a statistical value). You cannot say 'I have three 오답률' (오답률이 세 개 있어요); you should say 'I have three 오답' (오답이 세 개 있어요). Conversely, you wouldn't say 'The wrong answer of the class is 20%'; you would say 'The wrong answer rate (오답률) of the class is 20%'.

❌ 오답률을 세 개 틀렸어요. (Incorrect)
✅ 오답이 세 개예요. (Correct - I have three wrong answers.)

Contextual misuse is also common. Sometimes learners use '오답률' when they actually mean '실수' (mistake). '오답률' is strictly for formal evaluations and tests. If you accidentally take the wrong bus, you wouldn't say your 'bus-taking 오답률' is high; you would just say you made a '실수' (mistake). Keep '오답률' for scenarios involving questions, answers, and data.

❌ 이번 시험에서 오답률을 많이 했어요. (Incorrect - You don't 'do' a rate.)
✅ 이번 시험에서 오답이 많았어요. (Correct - I had many wrong answers.)

Lastly, be careful with the direction of the rate. A 'high' (높은) 오답률 is a negative thing for the student (meaning they failed a lot) but indicates a 'hard' (어려운) question. Sometimes learners get confused and think a high rate means a high score. Always remember: High 오답률 = Lots of people got it wrong = Hard question.

To broaden your Korean vocabulary, it is helpful to look at words that are related to 오답률. The most direct counterpart is 정답률 (Jeong-dap-ryul), which means 'correct answer rate.' In many reports, these two are used interchangeably depending on the focus. If the goal is to highlight success, they use 정답률; if the goal is to highlight the difficulty of a challenge, they use 오답률.

정답률 (Correct Answer Rate): Focuses on how many people got the answer right. (e.g., 정답률이 90%라면 쉬운 문제입니다. If the correct answer rate is 90%, it's an easy question.)
틀린 개수 (Number of wrong answers): A more casual way to talk about errors. Used by individuals rather than statisticians. (e.g., 몇 개 틀렸어? How many did you get wrong?)

Another related term is 난이도 (Nan-i-do), which means 'difficulty level.' While 오답률 is a statistical measurement, 난이도 is the descriptive quality of the task. A high 오답률 is evidence of a high 난이도. In news articles, you'll often see: '높은 오답률이 시험의 높은 난이도를 증명했다' (The high incorrect answer rate proved the high difficulty level of the exam).

이번 모의고사는 정답률보다 오답률 분석에 더 집중해야 합니다. (For this mock exam, we need to focus more on the incorrect answer rate analysis than the correct answer rate.)

In professional or academic writing, you might also encounter 오류율 (O-ryu-yul), which means 'error rate.' While '오답률' is specific to 'answers' (답) in a test, '오류율' is broader and can be used for software bugs, manufacturing defects, or linguistic errors in a corpus. If you are talking about a machine making mistakes, use 오류율. If you are talking about a student failing a question, use 오답률.

시스템의 오류율은 낮지만, 사용자의 오답률은 높습니다. (The system's error rate is low, but the user's incorrect answer rate is high.)

Understanding these distinctions allows you to choose the most precise word for your context. Using '오답률' in a test context shows you understand the specific nuances of Korean academic culture, whereas using '오류율' shows a more technical, general-purpose vocabulary.

How Formal Is It?

Wusstest du?

The spelling rule for '률' vs '율' is one of the most tested grammar points in Korean schools. It depends entirely on the batchim (final consonant) of the preceding syllable.

Häufige Fehler

Writing '오답율' instead of '오답률'. → 오답률
The spelling rule requires '률' after the consonant 'ㅂ'. This is a very common mistake even for natives.
Using '크다' (big) instead of '높다' (high) for the rate. → 오답률이 높다.
In Korean, rates and percentages are described as 'high/low' (높다/낮다), not 'big/small'.
Confusing '오답' (the answer) with '오답률' (the rate). → 오답이 세 개예요. (I have three wrong answers.)
You can't have 'three error rates' if you just mean three wrong answers. Use '오답' for the count.
Pronouncing it as [오답률] without nasalization. → [오담뉼]
Failing to nasalize makes the speech sound robotic and unnatural. The 'ㅂ' and 'ㄹ' should blend.
Using '오답률' for mechanical errors. → 오류율 (Error rate)
'오답률' is specifically for 'answers' (답). For machines or systems, use '오류율'.

Tipps

The 'Batchim' Rule

Remember: No batchim or 'ㄴ' batchim = 율. Other batchims = 률. Since '답' has 'ㅂ', use 률.

Nasalization

Don't say 'O-dap-ryul' clearly. Let the sounds blend into [O-dam-nyul] for a native sound.

Wrong-Answer Notebook

In Korea, students use an '오답 노트' (wrong-answer notebook) to lower their '오답률'. It's a great study method!

Business Usage

Use '오답률' when reporting on staff training results to sound professional.

Pairing

Always pair '오답률' with '높다' (high) or '낮다' (low).

Data Focus

When analyzing a test, look at the '오답률' to find your weakest subjects.

Antonym Check

If the '오답률' is 30%, the '정답률' is 70%. Use both to provide a full picture.

Exam Talk

Use this word when talking to Korean friends about exams; it shows you understand their academic culture.

Particle Use

Use '-의' to link a subject to its error rate, e.g., '수학의 오답률'.

Killer Questions

If you see a question with an '오답률' over 80%, don't feel bad if you get it wrong—it's a 'killer question'!

Einprägen

Eselsbrücke

Think of 'O' as 'Oh no!' (error), 'Dap' as 'Dapper' (a dapper student giving an answer), and 'Ryul' as 'Rule' (the statistical rule of the test). 'Oh no! The dapper student's rule says the error rate is high!'

Visuelle Assoziation

Häufig gestellte Fragen

10 Fragen

It is always '오답률'. According to Korean spelling rules, '-률' is used after a consonant (except 'ㄴ'), and '-율' is used after a vowel or 'ㄴ'. Since '답' ends in 'ㅂ', '률' is correct.

You divide the number of students who got the question wrong by the total number of students who took the test, then multiply by 100. For example, if 80 out of 100 students got it wrong, the 오답률 is 80%.

It depends on the perspective. For a student, a high personal 오답률 is bad. For a teacher or test-maker, a high 오답률 for a specific question indicates that the question was very difficult or challenging.

No, for software bugs or technical errors, '오류율' (error rate) or '버그 발생률' is more appropriate. '오답률' is strictly for 'answers' (답) in a test or survey.

In Korea, a 'Killer Question' (킬러 문항) is a question with an extremely high 오답률 (often 80-90% or more) designed to differentiate between the very top students.

It is pronounced as [오담뉼]. The 'ㅂ' in '답' changes to 'ㅁ' and the 'ㄹ' in '률' changes to 'ㄴ' because of the nasalization rule in Korean phonology.

While most common in schools, it also applies to any evaluation where there are 'right' and 'wrong' answers, such as driving tests, corporate training quizzes, or psychological surveys.

'오답률' is the rate of 'wrong answers' (specific to evaluations). '오류율' is a general 'error rate' (can apply to machines, data, or language).

Because of the competitive nature of the CSAT (Suneung). Since one or two questions can determine a student's university, analyzing which questions had high error rates is crucial for future test preparation.

While people might understand you, it is much more natural to say '오답률이 높다' (The error rate is high). Rates and percentages in Korean usually pair with '높다/낮다' (high/low).
