There is no specific rule or requirement regarding the number of groups in a grouped frequency distribution. The number of groups should be selected based on the range of the data and the level of detail desired in the distribution. However, having fewer than 5 groups may result in a distribution that is too simple and not reflective of the variability in the data, while having more than 20 groups may result in a distribution that is too complex and difficult to interpret. As a general guideline, it is recommended to have between 5 and 20 groups in a grouped frequency distribution, but the exact number should be chosen based on the specific characteristics of the data.
