Variable:某物或某人的某一特征和其他个体不同。 quantitative variables:定量变量either discrete(可以被数)or continuous.(A continuous variable is a variable whose possible values form some interval of Numbers)Typically, a continuous
在定量变量中,有些是离散的不能够连续的,称为离散变量(或非连续性变量,discrete or uncontinuous variable),这类型的变量只能取到的是某些特定的值,他们之间存在着一些“间隔/间隙”。比如,旅游的日程只有4天、5天、7天等,而有些是...

A random variable is a variable where chance determines its value. They can take on either discrete or continuous values.

Quantitative variables are classified as either discrete or continuous and we can distinguish them based on the minimum size of the unit of measurement. For a discrete variable, the minimum-sized unit is one and cannot be subdivided further. On the other hand, the...

(2)在定量变量中也存在着一些规律,有些变量是离散的不能够连续的,称为离散变量(或非连续性变量,discrete or uncontinuous variable),这这类型的变量只能取到的是某些特定的值,而且这些值之间存在着一些“间隔/间隙”。比如,休假的日期只可以是4天、5天、7天等,一天每小时到达北京火车站的火车的数量等。 不过,...
