Question

find the mean of all factors of 10

Answer 1

Factors of 10 = 1, 2, 5 and 10

Mean = Sum of all observations / Total no. of observations

= 1 + 2 + 5 + 10 / 4

= 18/4

= 4.5

Answer 2

Factors of 10 = 1,2,5,10.

We know that Mean = Sum of observations/No of observations

                                   = 1 + 2 + 5 + 10/4

                                   = 18/4

                                   = 4.5.



Hope this helps!
