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

**Answer/ Explanation**

Answer: (a)

**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

**Answer/ Explanation**

Answer: (d)

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

**Answer/ Explanation**

Answer: (b)

**4) The median of the data: 155 160 145 149 150 147 152 144 148 is**

a. 149

b. 150

c. 147

d. 144

**Answer/ Explanation**

Answer: (a)

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

**Answer/ Explanation**

Answer: (c)

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

**Answer/ Explanation**

Answer: (b)

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

**Answer/ Explanation**

Answer: (c)

**8) The collection of information, collected for a purpose is called:**

a. Mean

b. Median

c. Mode

d. Data

**Answer/ Explanation**

Answer: (d)

**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

**Answer/ Explanation**

Answer: (d)

Explanation: Mean = (2+3+4+5+0+1+3+3+4+3)/10 = 28/10 = 2.8

**10) Which of the following is not a measure of central tendency?**

a. Standard deviation

b. Mean

c. Median

d. Mode

**Answer/ Explanation**

Answer: (a)
