Solution
The data type for the variable "The number of phone calls made by Victorians in a day" is numerical discrete. This is because the number of phone calls can be counted in whole numbers and cannot be a fraction.
The appropriate visualization tool for discrete data is a bar chart. This is because a bar chart can clearly represent the frequency of each number of phone calls made.
