Suppose the first class in a frequency table of quantitative data is 0 dash 40-4 and the second class is 5 dash 95-9. what is the class midpoint of the first class?

To get the class midpoint or the middle value of this problem, we need to get the average of the lower class and the upper class.So in formula it is = upper + lower / 2Our lower class is 0 while the upper class is 4. So 4 + 0 = 4/2 = 2 would be the answer.
