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’_is 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’_is 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)
