Mean is the average so add all 5 together then divide by 5: 82
Median is the number in the middle if you order them least to greatest: 85
Mode is the number that occurs most often: there is no mode because they all occur once.

mean is an average so, here you add the 5 numbers and divide by 5 (tht total number) and get 82
median is the average middle so, here, you lay out the 5 numbers from low to high (60, 75, 85, 90, 100). here, to find the median, use the formula (n +1)/2. here, n = 5 so, this is (5+1)/2 or 6/2 or 3. So, the value in the 3rd position or 858 is the median.
mode is the most frequently occurring number in a group of numbers. Here, there is no duplicating number so, no mode number.

first put the number in order=100,90,85,75 and 60
1)100+90+85+75+60=410
410 divided by 5=82
2)median=median is always the number in the middle..so the answer is 85
3)mode is always the biggest number ...so the answer is 100

We're doing this in school, erm...
mean=100+75+85+90+60divided by the number of numbers =5
==410divided by5=82
mean=82
Forgotten how to do median and mode, sorry :(

Mean (average) is sum divided by numbers. 82 in this case.
Median = 85.
There is no mode.
