What is frequency and frequency distribution?

Answer 1

Frequency is how often something occurs. Frequency distribution is how often something occurs within a group of separate categories or ranges. Say you had a list of exam scores from a class of students. You might want to find out how many people got between 0% and 10%, how many got between 11% and 20%, how many got between 21% and 30%, and so on. All you are interested in is the how many as compared to who actually got the scores. What you would be doing is creating a frequency distribution table. You would be finding out how many people got results in the various ranges, or how the frequency of results are distributed across these ranges.
