Q:
# median mode mean and range on 84 45 10 28 75 63 16 55

Accepted Solution

A:

PUT THIS SET IN ORDER FROM LEAST TO GREATEST:

10, 16, 28, 45, 55, 63, 75, 84

__________________

MEDIAN: Find the number in the middle of the set.

10, 16, 28, 45, 55, 63, 75, 84

There cannot be two medians, so you find the number between 45 & 55.

MEDIAN = 50

_________________

MEAN: Find the average by adding up all of the numbers and dividing them by how many numbers there are.

10 + 16 + 28 + 45 + 55 + 63 + 75 + 84 = 376

376/8 = 47

MEAN = 47

________________

MODE: The number that occurs most often. If no number repeats, there's no mode.

THERE IS NO MODE

________________

RANGE: The difference between the largest and smallest value in the set. Subtract the largest (84) and smallest (10) value.

84 - 10 = 74

RANGE = 74

10, 16, 28, 45, 55, 63, 75, 84
