Explanation:

Step1: Arrange scores in ascending order

$72\%, 74\%, 76\%, 78\%, 80\%, 82\%, 92\%, 92\%$

Step2: Identify middle - two values

Since there are 8 (an even number) scores, the middle two values are the 4th and 5th values. The 4th value is $78\%$ and the 5th value is $80\%$.

Step3: Calculate the median

Median=$\frac{78 + 80}{2}\%=\frac{158}{2}\% = 79\%$
