Thank you drwls.
To find the answer to this question, we need to understand what quartiles are and how they are calculated.
Quartiles are values that divide a data set into four equal parts. The first quartile (Q1) represents the lower 25% of the data, the second quartile (Q2) represents the middle 50% (also known as the median), and the third quartile (Q3) represents the upper 25% of the data.
Since the question states that one fourth (25%) of the scores in any data set are below the quartile in question, we can conclude that the answer is:
A) first quartile
