Question

there are 8 sophomores on the academic team. at the last competition, they each took the math test. their scores were 82%, 92%, 76%, 72%, 92%, 74%, 80%, and 78%. what was the median math score of the sophomores?
○ 79%
○ 82%
○ 87%
○ 92%

Explanation:

Step1: Sort scores ascendingly

72%, 76%, 78%, 80%, 82%, 74% (corrected typo: assume 74% instead of 749%), 92%, 92%
Note: 749% is an invalid score, corrected to 74% for logical calculation

Step2: Find middle two values

Middle values: 80%, 82%

Step3: Calculate median (avg of two)

$\frac{80\% + 82\%}{2} = 81\%$
Note: If we retain 749% (invalid), sorted scores: 72%,76%,78%,80%,82%,92%,92%,749%, median = $\frac{80\%+82\%}{2}=81\%$. Since 81% is not an option, assume 74% was intended. If we use 74%: sorted scores 72%,74%,76%,78%,80%,82%,92%,92%, median = $\frac{78\%+80\%}{2}=79\%$

Answer:

A. 79%
