-{{ :数据的特性.jpg?500 |}}
-  * 集中量数：分布的中间位置的情况，也叫集中趋势，用来估计和预测总体的情况。
-  * 差异量数：描述数据分布的变异性，是对分布的延伸和聚集状态程度的定量化描述，用来衡量估计和预测的误差大小。
-:!:**学习要点**：
+{{ :第三章:data.svg?500 |}}
-  - 学会计算均值，中数和众数
+  * Central tendency: The situation at the middle position of a distribution, also known as concentration trend, used to estimate and predict the overall situation.
-  - 对于给定的分数分布，确定如何选用适宜的集中量数
+  * Variability: describes the variability of data distribution, is a quantitative description of the extension of distribution and the degree of aggregation, used to measure the size of estimation and prediction errors.
-  - 学会计算标准差,四分位距和全距
-  - 对于给定的分数分布，确定如何选用适宜的差异量数
