Question

Forty students took a statistics exam having a maximum of 50 points. The distribution of score is given in the stem-and-leaf plot.

Answer 1

Based on the fact that Tess's score was 25 in the statistics exam as shown by the stem-and-leaf plot, her Tess's percentile was 30th.

What was Tess's percentile?

Tess's percentile depends on the number of people whose scores she is above.

When looking at the stem-and-leaf plot, we see that Tess's score of 25 is the 13th score.

Her percentile is therefore:

= (13 - 1) / 40

= 12 / 40

= 30th percentile

Rest of the question is:

Tess’s score was 25. What was her percentile?
