WebClass interval is a term that is used to denote the numerical width of a class in a frequency distribution. In a grouped frequency distribution, data is arranged in the form of a class.

WebStep 1: We write the first and last number of the interval, which are the endpoints of the interval. For example, if the interval is from 6 to 20, we write 6, 20. Step 2: We use a round or square bracket on each side of the two numbers. We use: A square bracket [ ], if we want to include the endpoints.

WebIn statistics, interval estimation is the use of sample data to estimate an interval of possible values of a parameter of interest.
