Answer:

See Explanation

Explanation:

The question is incomplete, as the box plot is not attached.

However, the interpretation of the question is to determine the inter-quartile range (IQR) ; this represents the middle 50% of scores

To answer this question, I will make use of the attached box plot.

IQR is calculated as:


IQR = Q_3 - Q_1


Q_1 and
Q_3 are represented by the vertical edges of the rectangle in the box plot. [See attachment]

Reading
Q_1 and
Q_3, we have:


Q_1 = 37


Q_3 = 50

The IQR is:


IQR = 50 - 37


IQR = 13

Hence, the range that describes the middle 50% of the attached plot is 13
