### Measures of Central Tendency MCQs

ML Aggarwal Class 10 ICSE Maths Solutions

**Question 1. **If the classes of a frequency distribution are 1-10, 11-20, 21-30, …, 51-60, then the size of each class is

(a) 9

(b) 10

(c) 11

(d) 5.5

**Answer :**

In the classes 1-10, 11-20, 21-30, …, 51-60,

the size of each class is 10. (b)

**Question 2. **If the classes of a frequency distribution are 1-10, 11-20, 21-30,…, 61-70, then the upper limit of the class 11-20 is

(a) 20

(b) 21

(c) 19.5

(d) 20.5

**Answer :**

In the classes of distribution, 1-10, 11-20, 21-30, …, 61-70,

upper limit of 11-20 is 20-5 as the classes after adjustment are

0.5-10.5, 10.5-20.5, 20.5-30.5, … (d)

**Question 3. **In a grouped frequency distribution, the mid-values of the classes are used to measure which of the following central tendency?

(a) median

(b) mode

(c) mean

(d) all of these

**Answer :**

In a grouped frequency distribution,

the mid-values of the classes are used to measure Mean (c)

**Question 4. **In the formula: for finding the mean of the grouped data, d’_{i}s are deviations from a (assumed mean) of

(a) lower limits of the classes

(b) upper limits of the classes

(c) mid-points of the classes

(d) frequencies of the classes

**Answer :**

The formula is the finding of mean of the grouped data, d’_{i}s are mid-points of the classes

**Question 5. **Construction of a cumulative frequency distribution table is useful in determining the

(a) mean

(b) median

(c) mode

(d) all the three measures

**Answer :**

Construction of a cumulative frequency distribution table

is used for determining the median, (b)

**Question 6. **Consider the following frequency distribution:

The upper limit of the median class is

(a) 17

(b) 17.5

(c) 18

(d) 18.5

**Answer :**

From the given frequency upper limit of median class is 17.5

as total frequencies 13 + 10 + 15 + 8 + 11 = 57

(57 + 1)/2 = 58/2

= 29

and 13 + 10 + 15 = 28 where class is 12-17

But actual class will be 11.5-17.5

Upper limit is 17.5 (b)

**Question 7. **For the following distribution:

The sum of lower limits of the median class and modal class is

(a) 15

(b) 25

(c) 30

(d) 35

**Answer :**

From the given distribution

Sum of frequencies = 10 + 15 + 12 + 20 + 9 = 66

and median is (66/2) = 33

Median class will be 10-15 and modal class is 15-20

Sum of lower limits = 10 + 15 = 25 (b)

**Question 8. **An ogive curve is used to determine

(a) range

(b) mean

(c) mode

(d) median

**Answer** :

An ogive curve is used to find median. (d)
