Answer:
(b)Categorical Data
Step-by-step explanation:
The response, frequency, and calculation of the relative frequency of the data is given in the table below.
[tex]\left|\begin{array}{c|c|c}$Response&$Frequency &$Relative Frequency\\---&----&---\\$Below Average& 7&\dfrac{7}{15} \times 100 \approx 47\% \\&&\\$Average&5&\dfrac{5}{15} \times 100 \approx 33\%\\&&\\$Above Average&3&\dfrac{3}{15} \times 100 =20\%\\---&---&---\\$Total&15&100\end{array}\right|[/tex]

A quick way to determine if a data is categorical or numerical is to determine if the mean of the data can be found.
In this case, we cannot determine the mean of the data, therefore, it is a categorical data.
