The midterm score of 45 is the<u> 3rd decile,</u> meaning that 42% of the Senior High School students scored below this test.
<h3>What is a decile?</h3>
Deciles are a type of percentile that divides data into groups of 10%. That is, each decile comprises 10% of the dataset.
To determine the decile, sort the data from lowest to highest. Now, divide the result by ten. This number reflects the no. of observed values within each decile.
Sorting the data from lowest to highest, we have:
- 37, 43, 45, 61, 63, 74, 75, 76, 82, 87, 89, 98, 99, 100
= 14/10
= 1.4
Thus, each decile contains only a 1.4 score.
