Q 1 - Find the mean of the following symmetric distribution.
2, 2, 4, 4, 5, 5, 6, 6, 8, 8
Answer : A
Explanation
Step 1:
Mean of distribution = $\frac{(2 + 2 + 4 + 4 + 5 + 5 + 6 + 6 + 8 + 8)}{10} = \frac{50}{10}$ = 5
Step 2:
Or mean of middle two numbers = $\frac{(5 + 5)}{2}$ = 5
So mean of symmetric distribution = 5
Show Answer
Q 2 - Find the mean of the following symmetric distribution.
0, 0, 3, 3, 5, 7, 9, 9, 12, 12
Answer : C
Explanation
Step 1:
Mean of distribution = $\frac{(0 + 0 + 3 + 3 + 5 + 7 + 9 + 9 + 12 + 12)}{10} = \frac{60}{10}$ = 6
Step 2:
Or mean of middle two numbers = $\frac{(5 + 7)}{2}$ = 6
So, mean of symmetric distribution = 6
Show Answer
Q 3 - Find the mean of the following symmetric distribution.
1, 1, 4, 4, 5, 6, 7, 7, 10, 10
Answer : D
Explanation
Step 1:
Mean of distribution = $\frac{(1 + 1 + 4 + 4 + 5 + 6 + 7 + 7 + 10 + 10)}{10} = \frac{55}{10}$ = 5.5
Step 2:
Or mean of middle two numbers = $\frac{(5 + 6)}{2}$ = 5.5
So mean of symmetric distribution = 5.5
Show Answer
Q 4 - Find the mean of the following symmetric distribution.
0, 0, 2, 2, 3, 4, 5, 5, 7, 7
Answer : B
Explanation
Step 1:
Mean of distribution = $\frac{(0 + 0 + 2 + 2 + 3 + 4 + 5 + 5 + 7 + 7)}{10} = \frac{35}{10}$ = 3.5
Step 2:
Or mean of middle two numbers = $\frac{(3 + 4)}{2}$ = 3.5
So mean of symmetric distribution = 3.5
Show Answer
Q 5 - Find the mean of the following symmetric distribution.
3, 3, 5, 5, 6, 6, 7, 7, 9, 9
Answer : B
Explanation
Step 1:
Mean of distribution = $\frac{(3 + 3 + 5 + 5 + 6 + 6 + 7 + 7 + 9 + 9)}{10} = \frac{60}{10}$ = 6
Step 2:
Or mean of middle two numbers = $\frac{(6 + 6)}{2}$ = 6
So mean of symmetric distribution = 6
Show Answer
Q 6 - Find the mean of the following symmetric distribution.
3, 3, 5, 5, 6, 7, 8, 8, 10, 10
Answer : A
Explanation
Step 1:
Mean of distribution = $\frac{(3 + 3 + 5 + 5 + 6 + 7 + 8 + 8 + 10 + 10)}{10} = \frac{65}{10}$ = 6.5
Step 2:
Or mean of middle two numbers = $\frac{(6 + 7)}{2}$ = 6.5
So, mean of symmetric distribution = 6.5
Show Answer
Q 7 - Find the mean of the following symmetric distribution.
1, 1, 3, 3, 4, 4, 5, 5, 7, 7
Answer : C
Explanation
Step 1:
Mean of distribution = $\frac{(1 + 1 + 3 + 3 + 4 + 4 + 5 + 5 + 7 + 7)}{10} = \frac{40}{10}$ = 4
Step 2:
Or mean of middle two numbers = $\frac{(4 + 4)}{2}$ = 4
Mean of symmetric distribution = 4
Show Answer
Q 8 - Find the mean of the following symmetric distribution.
2, 2, 4, 4, 5, 6, 7, 7, 9, 9
Answer : D
Explanation
Step 1:
Mean of distribution = $\frac{(2 + 2 + 4 + 4 + 5 + 6 + 7 + 7 + 9 + 9)}{10} = \frac{55}{10}$ = 5.5
Step 2:
Or mean of middle two numbers = $\frac{(5 + 6)}{2}$ = 5.5
So mean of symmetric distribution = 5.5
Show Answer
Q 9 - Find the mean of the following symmetric distribution.
3, 3, 5, 5, 6, 7, 8, 8, 10, 10
Answer : A
Explanation
Step 1:
Mean of distribution = $\frac{(3 + 3 + 5 + 5 + 6 + 7 + 8 + 8 + 10 + 10)}{10} = \frac{65}{10}$ = 6.5
Step 2:
Or mean of middle two numbers = $\frac{(6 + 7)}{2}$ = 6.5
So mean of symmetric distribution = 6.5
Show Answer
Q 10 - Find the mean of the following symmetric distribution.
1, 1, 3, 3, 4, 5, 6, 6, 8, 8
Answer : B
Explanation
Step 1:
Mean of distribution = $\frac{(1 + 1 + 3 + 3 + 4 + 5 + 6 + 6 + 8 + 8)}{10} = \frac{45}{10}$ = 4.5
Step 2:
Or mean of middle two numbers = $\frac{(4 + 5)}{2}$ = 4.5
So mean of symmetric distribution = 4.5
