Hi I’m having trouble with this math topic How changing a value affects the mean and median. My math problem is The monthly rent (in dollars) paid by 10 people are given below. The numbers are 795, 935, 960, 995, 1025, 1030, 1050, 1090, 1105

Answer 1

For the mean, add them up , then divide by 9
For the median, list them in order, the median is the number in the middle.

Answer 2

I’m sorry but I’ve got another question about the pre algebra..

The numbers of trading cards owned by eight middle school students are given: 293, 378, 441, 458, 482, 485, 529, 614

Suppose that the number 614 from this list changes to 486

What happens to the median? What happens to the mean?

Answer 3

The median now is (458+482)/2
If 614 changes to 486, the median stays the same, since 486 is still higher than the median

Bu the mean will be less, because the sum of the numbers will be less.
