Question 2

Students height in inches for 35 students are given below. Arrange the following data in an individual frequency sequence.

60 72 68 68 58 55 50 72 55 50 66 66
62 55 66 66 58 72 72 60 55 60 55 58
60 66 72 72 60 68 55 58 65 60 68 55

Answer:

In the form of frequency distribution, the given data can be arranged as follows.

Heights (in inches) Marks Frequency
50 2
55 7
58 4
60 6
62 1
65 1
66 5
68 4
72 6
\(\sum f\) = 36

Question 3

Find out the missing class interval.

Class-Interval Below 20 20−50 50−90 90−140 More than 140
Frequency 8 11 15 3 5

Answer:

In the above-mentioned question, the class interval has a different width. Therefore, the missing class interval cannot be established.

Question 4

Transfer given below cumulative frequency series to simple frequency series.

Marks No. of Students
Less than 10 12
Less than 30 19
Less than 50 26
Less than 70 48
Less than 90 57

Answer:

The cumulative frequency ‘less than’ is displayed in ‘simple frequency distribution’ form.

Class-Interval Frequency
0 – 10

10 – 30

30 – 50

50 – 70

70 – 90

10

19 − 12 = 7

26 − 19 = 7

48 − 26 = 22

55 − 45 = 10

Question 5

From the following data, arrange a frequency distribution table with classes 10-20, 20-30, etc.

25 10 12 26 10 32 36 31 41 55
22 31 36 38 25 11 12 25 42 48
47 37 45 54 42 35 37 32 65 75

Answer:

In the form of frequency distribution, the given data can be arranged as follows.

*Class Interval Telly Marks Frequency
10-20 5
20-30 5
30-40 10
40-50 6
50-60 2
60-70 1
70-80 1
\(\sum f\) = 30
