There are many ways to collect data. Usually, researchers need to work with samples of data- sets collected from the whole population data and analyze such sample data. One of the goals in descriptive statistics is to organize and describe raw data sets in systematic way so that it is easier to understand study and draw some meaningful conclusions from it. Frequency distribution is one such method of data organization. Shall there be some guideline that we should follow while constructing frequency distributions? If yes, how?
