MCQs from CBSE Class 9 Maths Chapter 14: Statistics

1) The ratio of sum of observations and total number of observations is called:
a. Mean
b. Median
c. Mode
d. Central tendency

2) The mean of x+2, x+3, x+4 and x-2 is:
a. (x+7)/4
b. (2x+7)/4
c. (3x+7)/4
d. (4x+7)/4

Explanation: Mean = (x+2+x+3+x+4+x-2)/4 = (4x+7)/4

3) The median of the data: 4, 6, 8, 9, 11 is
a. 6
b. 8
c. 9
d. 11

4) The median of the data: 155 160 145 149 150 147 152 144 148 is
a. 149
b. 150
c. 147
d. 144

Explanation: First arrange the data in ascending order.

144 145 147 148 149 150 152 155 160

Since, the number of observations here is odd, therefore,

Median = (n+1)/2 th = (9+1)/2 = 10/2 = 5th number = 149

5) The median of the data: 17, 2, 7, 27, 15, 5, 14, 8, 10, 24, 48, 10, 8, 7, 18, 28 is:
a. 10
b. 24
c. 12
d. 8

Explanation: Arrange the given data in ascending order:

2, 5, 7, 7, 8, 8, 10, 10, 14, 15, 17, 18, 24, 27, 28, 48

Since, the number of observations givere here is even, hence,

Median will be average of two middle terms.

n/2th = 16/2 = 8th term

(n/2 +1)th = (16/2 + 1)th = 9th term

Therefore,

Median = (10+14)/2 = 12

6) The mode of the given data: 4, 6, 5, 9, 3, 2, 7, 7, 6, 5, 4, 9, 10, 10, 3, 4, 7, 6, 9, 9 is;
a. 7
b. 9
c. 10
d. 6

Explanation: First arrange the data in order:

2, 3, 3, 4, 4, 4, 5, 5, 6, 6, 6, 7, 7, 7, 9, 9, 9, 9, 10, 10

Hence, mode = 9

7) The value which appears very frequently in a data is called:
a. Mean
b. Median
c. Mode
d. Central tendency

8) The collection of information, collected for a purpose is called:
a. Mean
b. Median
c. Mode
d. Data

9) The mean of the data 2, 3, 4, 5, 0, 1, 3, 3, 4, 3 is
a. 2
b. 2.2
c. 2.4
d. 2.8
