Question

I have 28 students in my MAT121 class who recently took a test. Their results are graphed below.

Answer 1

Considering the box-and-whisker plot, it is found that:

a) 25% of the students scored less than 60.

b) 25% of the students received a score greater than 85.

What does a box-and-whisker plot shows?

A box and whisker plot shows three things:

• The 25th percentile, which is the median of the bottom 50%.

• The median.

• The 75th percentile, which is the median of the upper 50%.

From the plot given in the graph, we have that:

• The 25th percentile is of 60, hence 25% of the students scored less than 60.

• The 75th percentile is of 85, hence 25% of the students received a score greater than 85.
