The frequency distribution of a variable x is xi : 2 3 1 5 fi : 1 2 3 1 then the mean is ans.
Question
Solution 1
The mean (or average) of a frequency distribution can be calculated using the formula:
Mean = Σ(xi * fi) / Σfi
Where: xi = value of the variable fi = frequency of the variable
Let's calculate:
Mean = [(21) + (32) + (13) + (51)] / (1 + 2 + 3 + 1) Mean = [2 + 6 + 3 + 5] / 7 Mean = 16 / 7 Mean Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
