Answer:

Mean: 88

Median:93

Explanation:

To find the mean, add all the numbers to get the sum, then divide by how many numbers there are.

Put the numbers from smallest to largest, then find the number in the middle if there’s an odd amount of numbers. If there is an even amount of numbers, find the two in the middle, add them together, and divide by 2 to get the median.

Mean: 76+82+54+100+100+82+100+93+100+93 = 880/10 = 88

Median: 54, 76, 82, 82, 93, 93, 100, 100, 100, 100

There is an even amount of numbers (10)

The two in the middle are 93 and 93

93+93=186/2=93
