Using the percentile concept, it is found that 10 students scored lower than he did.
<h3>What is the meaning of the percentile of a measure?</h3>
When a measure is in the xth percentile of a data-set, it is greater than x% of the measures and lesser than (100 - x)%.
In this problem, he scored on the 20th percentile, that is, higher than 20% of the 50 students. Then:
0.2 x 50 = 10.
10 students scored lower than he did.
