The given data is numerical.
Explanation of Solution
Given:
A teacher recorded the test score of each student in a class.
Calculation:
We know that a data type which can be expressed in numbers is known as numerical data.
The test score of each student will be expressed in numbers, therefore, the given data is numerical data.
We know that line plots, scatter plots, bar graphs and stem and leaf plots are used to represent numerical data.
Therefore, we can use line plots, scatter plots, bar graphs and stem and leaf plots to display the given data.
