A. Lower quartile
B. Upper quartile
C. Median
D. 70th percentile

Answers

Lower quartile. The correct option is A

What is Lower quartile ?

The lower quartile, often known as the first quartile or Q1, is a measure of central tendency that separates the bottom 25% of a data set from the rest of the data.

In this instance, five out of the 20 students received scores of 70 or lower, which equals a 25% proficiency rate.

Therefore, 70 or below is the lower quartile.
