Question

Median mode mean and range on 84 45 10 28 75 63 16 55

Answer 1

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

Answer 2

Mean: 47. Mean is when you add up all the numbers, then divide by how many numbers you added (adding them together you get 376, which you divide by 8).

Median: 50. Median is when you sort every number numerically and find which number is in the middle. Since there are 8 numbers, there are 2 numbers you'd find the number equally in between each of those 2 numbers. That number being 50.

Mode: There is no mode. Mode is the number that is "most frequent" or is repeated the most in the number sequence.

Range: 74. Range is when you subtract the smallest number of the sequence from the largest number.

I hope this helps!
