What are bar charts?
A bar chart is a chart or graph that presents categorical data with rectangular bars with weights proportional to the values that they represent. These bars are spaced in between compared to histograms that are not spaced.
According to the given data, the x-axis of the bar graph will be the range of dollars collected by students while the y-axis will represent the number of students in each category.
Using an interval of 5;
From 10 - 15, there are 14 students
From 20 -25, there are 11 students
From 30 - 35, there are 6 students
From 40 - 45, there are 3 students
From 50 upwards, there are 2 students
The equivalent bar chart that represents the data is attached below;
Note that the count is equivalent to the number of students while the categories are the allowance in dollars
