We’ve listed key characteristics here: Now that you know how to spot the interval scale when you see it, let’s take a look at some useful interval scale examples. Interval measurement allows you to calculate the mean and median of variables. Knowing the measurement level of your data helps you to interpret and manipulate data in the right way. Interval data can be discrete with whole numbers like 8 degrees, 4 years, 2 months, etc., or continuous with fractional numbers like 12.2 degrees, 3.5 weeks or 4.2 miles.
