Question

The following dataset represents the math test scores for a class of 20 students.90, 85, 95, 100, 100, 90, 100, 65, 100, 85, 80, 95, 80, 100, 85, 75, 100, 90, 90, 75Would the mode be a good measure of central tendency for this dataset?

Answer 1

We shall begin by arranging the data set in ascending order;

$\begin{gathered} 65,75,75,80,80,85,85,85,90,90,90,90,95,95,100,100,100,100,100,100 \\ \text{The mode in this data set is 100} \\ The\text{ answer is NO} \\ No,\text{ since there are many more data values below the Mode than above} \end{gathered}$

The answer is;

No, since there are many more data values below the mode than above
