Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
A histogram shows the number of students scoring within certain ranges. If the bar for the range 50-59 has a height of 12 units and each unit represents 2 students, what is the frequency of students scoring between 50 and 59?
[2 marks]2.
The bar for scores 60-69 in a histogram is 15 units high. Each unit equals 3 students. What is the class frequency for this range?
[2 marks]3.
Calculate the total number of students who scored between 40 and 69, given that the bar for 40-49 is 10 units high (each unit = 2 students), and for 70-79 is 8 units high (each unit = 4 students).
[3 marks]4.
A histogram has a bar height of 18 units for the class 80-89. If each unit represents 2 students, what is the class frequency?
[2 marks]5.
The total number of students in classes 30-39 and 40-49 is 50. If the bar for 30-39 is 7 units high (each unit = 3 students), what is the bar height for 40-49, given it has 15 students more?
[3 marks]6.
A histogram shows the number of cars passing a checkpoint each hour. The bar for 9-10 am is 20 units high and each unit equals 1 car. How many cars passed between 9 and 10 am?
[2 marks]7.
In a histogram, if the bar for 70-79 is 12 units high (each unit = 2 students), what is the class frequency?
[2 marks]8.
A histogram displays data for ages. The bar for 20-29 has a height of 9 units, each representing 5 students. Find the class frequency for ages 20-29.
[2 marks]9.
Construct a histogram bar for the class 90-99 with a frequency of 30 students, given each unit height represents 2 students. How tall should the bar be?
[3 marks]10.
A histogram has a bar height of 14 units for the class 100-109. If each unit equals 3 students, what is the class frequency?
[2 marks]11.
Identify and correct the mistake: A student reports that a bar of height 10 units represents 20 students, assuming each unit equals 3 students.
