The mean

You have to first put the numbers in order

18,22,26,34,39,42

To find the median you have to find the number that's in the middle and since there are two of them, you have to find the average of them

26+34=60

60/2=30

Median is 30

To find the mean, you have to add everything together and then divide it by 6.

18+22+26+34+39+42=181

181/6 = 30.17

Now you have to add the 65

18,22,26,34,39,42,65

The middle number is 34

Median=34

18+22+26+34+39+42+65=246

246/7=35.14

Now you just have to subtract

new median-old median

34-30=4

New mean-old mean

35.14-30.17=4.97

So the mean will increase more
