The mean will increase from 14 to 20. The median will increase from 12 to 15.

Oh, dude, the median in algebra is like the middle value in a set of numbers when they're arranged in order. It's that one number that's chilling right in the middle, splitting the data set in half. So, if you're looking for the median, just find that cool, average Joe hanging out in the middle of the numbers.
Arrange the data from lowest to highest: 13 16 18 26 35 42 Normally the middle number is picked but because the set of data is even choose the middle two numbers add them up and divide by 2. 18+26 = 44 44/2 = 22 So the median is 22.
Arrange in order: 12 13 13 14 16 18 19 The median is the number in the middle, where there are are as many other numbers on one side as the other: Answer is median = 14
The mean will increase from 14 to 20. The median will increase from 12 to 15.
18. It is the middle number when they are listed in order.

First, to find median put numbers in order so: 5, 5, 6, 7, 8, 9, 10, ( 10, 12 ,) 14, 15, 17, 18, 18, 18, 20 10 + 12= 22 divided by 2= 11, the median is 11
One possibility: 5, 6, 7, 7, 7, 12, 12, 13, 14, 15, 16, 18

The variance of this data set is 22.611
It is the mid-point of a set of data in ascending order as for example 2 3 7 9 11 15 18 and so 9 is the median because it is at the centre
