Answer:

mean = 79

median = 77.5

mode = 75

Explanation:

mean is to add all numbers and then divide the sum by the total numbers given

mean = (75 + 75 + 80 + 86) / 4 = 316 / 4 = 79

median is to arrange all the numbers in ascending order, if the numbers are odd the middle one is the median, if the numbers are even the average of the middle two numbers is the median.

the median of = 75, 75, 80, 86

= (75 + 80) / 2 = 155 / 2 = 77.5

mode is the number in the data set that is coming most frequently throughout the data.

mode = 75
