Answer:
Range: 40
Mean: 75.5
Median (a.k.a. media): 75
Mode: 75
Step-by-step explanation:
1) Put the numbers in order
60
, 60
, 65
, 75
, 75
, 75
, 75
, 75
, 95
, 100
2) Find the range
To find the range, you subtract the largest number from the smallest number. In this case, it those are 100 and 60 respectively.
100-60 = 40 which means the range is 40.
3) Find the mean
To find the mean, you add all the numbers together and then divide that by the number of numbers. So...
60 + 60 + 65 + 75 + 75 + 75 +75 + 75 + 95 + 100 = 755
755/10 = 75.5
*You divide by 10 because there are 10 numbers*
That means your mean in 75.5.
4) Find the median (a.k.a. media)
To find the median, you must find the number that is in the middle when the numbers are in order.
In this case, we have two numbers in the middle 75 and 75. To find the median we must add these two numbers together and then divide by 2.
75 + 75 = 150
150/2 = 75
That means the median is 75.
5) Find the mode.
To find the mode, you must find the number(s) that appear the most. In this case, that would be 75 as it appears five times in this number set.
That means the mode is 75.
I hope this helps!
