Mean = (100+95+93+89+95+81+91)/7 = 92
To find the median, we need to arrange the numbers in order: 81, 89, 91, 93, 95, 95, 100. The median is the middle number, which is 93.
The mode is the number that occurs most frequently, which is 95. Mean = (100+95+93+89+95+81+91)/7 = 92
To find the median, we first need to put the scores in order:
81, 89, 91, 93, 95, 95, 100
There are 7 scores, so the median is the 4th score or 93.
The mode is the score(s) that appears most frequently. In this case, 95 appears twice and is the mode.
