Question

the lowest score on an exam was 68, the median score was 76, and the high score was 93. what was the range?
choose the correct answer below.
a. the range was 25, because that is the difference between the lowest score and the highest score.
b. the range was 76, because that is the median score.
c. the range was 76, because that is the difference between the median score and the highest score.
d. the range was 68, because that is the lowest score.
e. the range was 68, because that is the difference between the lowest score and the highest score.
f. the range was 25, because that is the difference between the lowest score and the median score.

Explanation:

Step1: Recall the formula for range

The range of a data set is calculated as \( \text{Range}=\text{Highest value}-\text{Lowest value} \).

Step2: Identify the highest and lowest values

Given that the lowest score \( L = 68 \) and the highest score \( H=93 \).

Step3: Calculate the range

Substitute the values into the formula: \( \text{Range}=93 - 68=25 \).

Answer:

A. The range was 25, because that is the difference between the lowest score and the highest score.
