What Are The Steps Taken In The Formation Of A Frequency Distribution?

Determine the largest and smallest values in the raw data and calculate range, which is the difference between largest and smallest value. There are no hand and fast rules for deciding the number of classes, which actually depends on the size of the date. When the data are sufficiently large. The number of classes should be between ten and twenty.
Approximate length of the class interval can be determined by the ratio of range and number of classes. In the case of fractional results, the next higher whole number may be used as class interval. The lower class limit should cover the smallest value in raw data.

Find the upper class boundary by adding the class interval to the lower class boundary. The remaining lower and upper class limits may be determined by adding the class interval.
If the given set of data is arranged in ascending or descending order, then observations are distributed among different classes by listing the actual observations. However, easiest method of tabulation the data is by recording a stroke opposite the appropriate class for each observation. The first four strokes are recorded vertically and the fifth one is recorded diagonally.
