## What is the number of classes in statistics?

For most data, 6 to 15 classes are enough. Class intervals (lengths) should be equal. Intervals such as 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, etc are desirable. The starting point for each class should be divisible by the interval, For example, in the class 15 - 20, the starting point, 15, is divisible by the interval, 5 ...
