A frequency distribution has class intervals 0-10, 10-20, 20-30, 30-40, and 40-50 with frequencies 7, 3, 12, 13, and 2. What is the less than cumulative frequency for the class less than 40?

2

A more than cumulative frequency distribution has class frequencies 2, 12, 22, 8, and 6 for the classes 0-10, 10-20, 20-30, 30-40, and 40-50. What is the more than cumulative frequency for more than 30?

3

A continuous series uses inclusive classes 10-19, 20-29, 30-39, and 40-49. What are the exclusive classes after applying the correction factor 0.5?

4

Sample Questions

1multiple choice

A continuous series has range 80 and 8 equal classes. What is the class width?

Show answer

10

Using n × h = R, where n = 8 and R = 80, we get h = 80 / 8 = 10.

2multiple choice
3 marks

A distribution has the smallest value 15 and the largest value 82. If 7 equal classes are chosen, what is the approximate class width using Width of Class-Interval = (Largest value - Smallest value) / Number of classes desired?

Show answer

9.57

Width = (82 - 15) / 7 = 67 / 7 = 9.57 approximately.

3multiple choice
3 marks

A frequency array has values 13, 14, 15, 16, 17, 18, 19, and 20 with frequencies 5, 5, 5, 4, 3, 4, 3, and 1. What is the total frequency after adding all classes?

Show answer

30

Add all frequencies: 5 + 5 + 5 + 4 + 3 + 4 + 3 + 1 = 30.

4multiple choice
3 marks

A class interval 80-120 has midpoint 100. If a value in the class is 109, what is its error of grouping when the midpoint is used as the class value?

Show answer

9

Error of grouping is the difference between the actual value and the midpoint. Here, 109 - 100 = 9.
