Number of goals
Frequency
0 1 2 3 4 5
5 8 12 10 2
4 How to calculate the mean value in such cases? In this case, we multiply the number of goals with frequency and then sum it so as to find the value of goals, while all the value of frequency should be added to find the value of number of observations (matches). Number of goals Frequency No. of goals X Frequency 0 4 0*4 = 0 1 8 1*8 = 8 2 12 2*12 = 24 3 10 3*10 = 30 4 2 4*2 = 8 5 4 5*4 = 20 Sum 40 90 Mean = 90/40 = 2.25
