The first thing to do before calculating the median value is write the 32 scores ordered from lowest to highest:
![47,52,55,57,62,63,63,65,65,66,70,72,74,74,74,74,75,75,77,77,79,80,81,82,83,85,86,90,92,94,94,97]()
The median is the value that divides the set in half. There are 32 scores so there have to be 16 smaller (or equal to) than the median and 16 bigger (or equal to) than it. A way to find it is by picking the 16th and the 17th scores, adding their values and then dividing the result by 2. These scores are 74 and 75 so the median is:
So the median value is 74.5.
The mode is the element of the set that appears most often. In this case it would be the score that is repeated the most. This score is 74 since it appears
