29, 25, 23, 22, 32, 29
Answer : A
Explanation
Step 1:
Mean of the data = $\frac{(29+25+23+22+32+29)}{6}$ = 26.67
Step 2:
Data set in increasing order − 22, 23, 25, 29, 29, 32
Median of data set = $\frac{(25+29)}{2} =\frac{54}{2}$ = 27
42, 40, 40, 47, 41
Answer : C
Explanation
Step 1:
Mean of the data = $\frac{(42 + 40 + 40 + 47 + 41)}{5}$ = 42
Step 2:
Data set in increasing order − 40, 40, 41, 42, 47
Middle score = 41; Median of data set = 41.
70, 68, 56, 62, 56, 66, 56
Answer : B
Explanation
Step 1:
Mean of the data = $\frac{(70+68+56+62+56+66+56)}{7}$ = 62
Step 2:
Data set in increasing order − 56, 56, 56, 62, 66, 68, 70
Middle score is 62
Median of data set = 62
47, 40, 51, 51, 54, 53
Answer : D
Explanation
Step 1:
Mean of the data = $\frac{(47+40+51+51+54+53)}{6}$ = 49.33
Step 2:
Data set in increasing order − 40, 47, 51, 51, 53, 54
Median of data set = $\frac{(51+51)}{2} = \frac{102}{2}$ = 51
31, 44, 39, 42, 43, 43
Answer : B
Explanation
Step 1:
Mean of the data = $\frac{(31+44+39+42+43+43)}{6}$ = 40.33
Step 2:
Data set in increasing order: 31, 39, 42, 43, 43, 44
Median of data set = $\frac{(42+43)}{2}$ = 42.5
78, 72, 83, 69, 84, 81, 81, 79
Answer : A
Explanation
Step 1:
Mean of the data = $\frac{(78+72+83+69+84+81+81+79)}{8}$ = 78.38
Step 2:
Data set in increasing order − 69, 72, 78, 79, 81, 81, 83, 84
Median of data set = $\frac{(79+81)}{2}$ = 80
94, 79, 81, 79, 87
Answer : D
Explanation
Step 1:
Mean of the data = $\frac{(94+79+81+79+87)}{5}$ = 84
Step 2:
Data set in increasing order − 79, 79, 81, 87, 94
Middle score = 81
Median of data set = 81
42, 37, 43, 39, 36, 40, 36
Answer : C
Explanation
Step 1:
Mean of the data = $\frac{(42+37+43+39+36+40+36)}{7}$ = 39.
Step 2:
Data set in increasing order − 36, 36, 37, 39, 40, 42, 43
Middle score 39
Median of data set = 39
57, 65, 72, 66, 55, 57, 58, 57, 62
Answer : A
