Convenience is the most common factor influencing a decision as to the size of class interval in a grouped frequency distribution. This is because the class intervals should be easy to work with and understand, and should also capture the important characteristics of the data distribution. Choosing convenient class intervals can make it easier to analyze and interpret the data. Factors such as the number of scores above the mean or the size of the mean and standard deviation may also be considered, but they are not as commonly used as convenience.
