Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
Given the grouped data: Class intervals 0-10, 10-20, 20-30, with frequencies 5, 12, 8 respectively. What is the modal class?
[2 marks]2.
Create a frequency table for the following data: Number of students per age group: 5-10, 11-15, 16-20; with frequencies 8, 15, 10.
[3 marks]3.
In a grouped data frequency table, the class interval 20-30 has the highest frequency. What is the modal class?
[2 marks]4.
Calculate the modal class for the following data: Class intervals 0-5, 5-10, 10-15, with frequencies 3, 7, 4.
[2 marks]5.
Plot the frequency distribution for the data: Class intervals 0-10, 10-20, 20-30 with frequencies 4, 9, 6. Draw the bar graph on the grid provided.
[4 marks]6.
Given the grouped data: Class intervals 0-10, 10-20, 20-30, 30-40 with frequencies 5, 15, 10, 7. What is the modal class?
[2 marks]7.
A class interval 50-60 has a frequency of 8, and 40-50 has a frequency of 12. Which class is the modal class?
[2 marks]8.
Identify and correct the mistake: In the frequency table, the class 20-30 has a frequency of 0, but it is marked as the modal class.
[3 marks]9.
Construct a grouped frequency table for data: Number of books read in a month: 0-2, 3-5, 6-8, with frequencies 4, 9, 6.
[3 marks]10.
Using the frequency table with class intervals 0-10, 10-20, 20-30, 30-40 and frequencies 4, 12, 9, 5, determine the mode class.
[2 marks]11.
A grouped data table shows class intervals 0-5, 5-10, 10-15, 15-20 with frequencies 6, 6, 3, 4. Which class is most likely the modal class?
