1. Data and Its Types | 数据及其类型

Data is information collected for analysis. It can be described as qualitative (categorical) when it describes qualities, like eye colour or type of car, and quantitative (numerical) when it involves numbers, like height or test scores.

数据是为分析而收集的信息。它可以被描述为定性（分类）数据，描述特征，如眼睛颜色或汽车类型；也可以是定量（数值）数据，涉及数字，如身高或考试成绩。

Quantitative data splits further into discrete data (countable values, e.g. number of students) and continuous data (measurable values along a scale, e.g. weight or time). Remember: discrete means you can count it; continuous means you measure it.

定量数据进一步分为离散数据（可数的值，如学生人数）和连续数据（沿刻度测量的值，如体重或时间）。记住：离散意味着可以计数；连续意味着需要测量
