Question

Two sets of values are given below.
set 1: 54 , 56 , 52 , 58 , 55
set 2: 58 , 56 , 51 , 56 , 54


Which of the following conclusions can be drawn about the means of these two sets?


A. The mean for set 2 is higher than the mean for set 1.

B. The mean for set 2 is lower than the mean for set 1.

C. The mean for set 2 is equal to the mean for set 1.

D. The medians of both sets are equal to the means of both sets.

Answer 1

Mean of set 1: (54+56+52+58+55)/5
= 55

Mean of set 2: (58+56+51+56+54)/5
= 55

Since the mean is the same for both sets, answer is C.
