WebOct 1, 2024 · The short answer: Time is considered an interval variable because differences between all time points are equal but there is no “true zero” value for time. For example, the difference between 1 PM and 2 PM is the same as the difference between 2 PM and 3 PM, which is the same as the difference between 3 PM and 4 PM, and so on. … WebContinuous variable [ edit] A continuous variable is a variable whose value is obtained by measuring, i.e., one which can take on an uncountable set of values. For example, a variable over a non-empty range of the real numbers is continuous, if it can take on any value in that range. The reason is that any range of real numbers between and with ...
