Overview

“代表性” (dài biǎo xìng) 是一个中文名词，意思是“serving as a typical example of something; representative”。它用来描述一个事物（如人、物、事件、数据等）是否能够典型地反映出其所属的群体、类别或整体的特征。一个具有代表性的样本或例子，能够帮助我们更好地理解和认识整体。例如，一个班级的平均成绩代表了这个班级的整体学习水平，如果这个平均成绩能够真实反映大多数同学的情况，那么它就具有代表性。

“代表性”常用于描述样本、例子、人物、数据、观点等。它可以作为主语、宾语或定语使用。常见的搭配有：具有代表性、缺乏代表性、代表性样本、代表性人物、代表性事件等。

  • 句式1：[事物] 具有/缺乏代表性。
  • 句式2：这是一个具有代表性的[事物]。
  • 句式3：我们需要找到有代表性的[事物]来研究。

**日常对话**: 简单地说明某件事物是否能体现某种普遍情况。例如，“他买的这款手机是今年的热门款，很有代表性。”

“代表”可以作动词（represent）或名词（representative）。作为名词时，指被推举出来代表集体或个人发言、行使权力的人或事物。而“代表性”是“代表”这个概念的名词化，强调的是“作为代表的性质或特征”。

  • 例句：他是我们公司的代表（名词）。这个设计方案很有代表性（名词，指其特征）。

“典型”更侧重于“typical”或“model”，强调事物作为一种标准或模式。它可以是形容词或名词。当用作名词时，与“代表性”相似，指具有典型特征的事物。但“代表性”更强调“representing”的含义，即代表整体的能力。

  • 例句：这是一个典型的中国家庭（形容词）。这个案例很有典型性（名词，同代表性）。

“象征”指用具体事物来表现某种特殊的意义、思想或精神。它强调的是符号意义和精神内涵，不一定需要代表整体的普遍特征。

  • 例句：和平鸽是和平的象征。

How to Use It

Notas de uso

The term '代表性' is widely used across various registers, from academic and formal discussions to everyday conversations. It's particularly important in contexts involving data, research, and analysis where the validity of generalizing from a sample to a population is key. Ensure that what you describe as 'representative' genuinely reflects the characteristics of the group or phenomenon it pertains to.

Erros comuns

A common mistake is to use '代表性' loosely without ensuring the subject truly exemplifies the larger group. For instance, claiming a single anecdote is 'representative' of a widespread issue without sufficient evidence. Also, confusing it with '典型' (typical) or '象征' (symbolic) can lead to imprecise meaning.

Tips

💡

Focus on Typicality

When using '代表性', think about whether the subject truly mirrors the larger group or concept it's associated with.

⚠️

Avoid Overgeneralization

Be cautious when claiming something has '代表性', especially if the sample size is small or the selection process is biased. It can lead to inaccurate conclusions.

🌍

Cultural Exemplars

In Chinese culture, identifying '代表性' figures or works is often important for understanding historical periods or cultural movements.

Origem da palavra

The word '代表性' is formed by combining '代表' (represent, delegate) with the abstract noun suffix '-性' (-ness, -ity). '代表' itself comes from '代' (on behalf of) and '表' (to show, express). The '-性' suffix turns the concept of 'representing' into a quality or characteristic.

Contexto cultural

In Chinese culture, identifying representative figures or achievements is often linked to national pride or cultural heritage. For example, certain historical figures, artistic styles, or scientific breakthroughs are highlighted for their '代表性' in showcasing Chinese civilization or progress.

Dica de memorização

Think of '代表性' as a 'representative' person who stands for their entire group. If that person truly embodies the group's traits, they have high 'representativeness'.
