可汗学院：统计学（视频版） You can have discrete random variables, or continuous. 你可以有离散的随机变量，也可以是连续的。 可汗学院：统计学（视频版） You have discrete, so finite meaning you can't have an infinite number of values for a discrete random variable. 你有离散的，所以有限意味着你不能为离散随机变量拥有无限数量的值。 可汗学院：统计学（视频版） Well, based on how we thought about the probability distribution functions for the discrete random variable, you'd say OK, let's see. 好吧，根据我们对离散随机变量的概率分布函数的看法， 你会说好吧， 让我们看看。 可汗学院：统计学（视频版） So it's important to realize that a probability distribution function, in this case for a discrete random variable, they all have to add up to 1. 所以重要的是要认识到概率分布函数，在这种情况下对于离散随机变量， 它们都必须加起来为 1。

Continuous and discrete variables（重定向自Discrete variable）
In mathematics, a variable may be continuous or discrete. If it can take on two particular real values such that it can also take on all real values between them (even values that are arbitrarily close together), the variable is continuous in that interval. If it can take on a value such that there is a non-infinitesimal gap on each side of it containing no values that the variable can take on, then it is discrete around that value. In some contexts a variable can be discrete in some ranges of the number line and continuous in others. |
