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

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 variable involves a measurement of something, such as the height of a ...
A random variable is a variable where chance determines its value. They can take on either discrete or continuous values, and understanding the properties of each type is essential in many statistical applications. Random variables are a key concept instatisticsand probability theory. While randomness...
Think about “hidden” numbers that you haven’t considered. For example: is time a discrete or continuous variable? You might think it’s continuous (after all, time goes on forever, right?) but if we’re thinking about numbers on a wristwatch (or a stop watch), those number...

If you're still unsure whether you're dealing with discrete or continuous data, consider asking yourself the following questions: Can you add up the data? Can you quantify the data? Can you break down the data and does it still make sense? Which is it: discrete or continuous variable?

State whether the variable is discrete or continuous. The temperature in degrees Fahrenheit on July 4th in Juneau, Alaska Continuous and Discrete Random Variables: Many statistical procedures begin by identifying the random variable and its type because each...
As in the time scales literature, we first derive discrete analogues of all the common continuous calculus functions with an eye to maintaining as much similarity as possible between these discrete analogues and their continuous forebears. For example, in order to maintain the crucial property that...
