- | 算数平均数是三种集中量数中最灵敏、最客观且最具有代表性的。 | + | **优点(Advantages):** |
- | ==== | + | |
- | ==== | + | 1、在计算算数平均数时将所有的数值都纳入了考虑范围,反应了分布的变异; |
+ | |||
+ | When calculating the arithmetic mean, all numerical values are considered, reflecting the variability in the distribution. | ||
+ | |||
+ | 2、算数平均数可以进行代数运算; | ||
+ | |||
+ | The arithmetic mean allows for algebraic operations. | ||
+ | |||
+ | 3、算数平均数是三种集中量数中最灵敏、最客观且最具有代表性的。 | ||
+ | |||
+ | The arithmetic mean is the most sensitive, objective, and representative measure among the three central tendency measures. | ||
+ | |||
+ | **缺点:**算数平均数的代表性会受到极端数值的影响。 | ||
+ | |||
+ | Disadvantages: | ||

+ | ==== | ||
+ | **优点(Advantages):**中数只和数据所处的位置有关,因此它不受极端数值的影响。 | ||
+ | |||
+ | The median is only influenced by the position of data, making it immune to extreme values. | ||
+ | |||
+ | **缺点(Disadvantages):** | ||
+ | |||
+ | 1、由于只和位置有关,因此中数对数据变动的反应不够灵敏; | ||
+ | |||
+ | Because it is solely position-dependent, | ||
+ | |||
+ | 2、中数不能进行代数运算。 | ||
+ | |||
+ | The median cannot undergo algebraic operations. | ||
+ | ---- | ||
+ | |||
+ | ==== | ||
+ | **优点(Advantages):** | ||
+ | |||
+ | 1、众数相对来说比较直观,容易理解; | ||
+ | |||
+ | The mode is relatively intuitive and easy to understand. | ||
+ | |||
+ | 2、众数不受极端值影响。 | ||
+ | |||
+ | (在命名型的数据中,一般来说只能用众数) | ||
+ | |||
+ | |||
+ | The mode is not affected by extreme values (typically used in nominal data). | ||
+ | |||
+ | **缺点(Disadvantages):** | ||
+ | |||
+ | 1、反应不够灵敏,代表性差于中数; | ||
+ | |||
+ | It is less sensitive and less representative than the median. | ||
+ | |||
+ | 2、不能进行代数运算; | ||
+ | |||
+ | It cannot undergo algebraic operations. | ||
+ | |||
+ | 3、要求数据分布有明显中心。 | ||
+ | |||
+ | The data distribution must have a clear central tendency. | ||
