The mean will increase from 14 to 20. The median will increase from 12 to 15.
When you have a set of data, the median is the middle number. If your data is this: 1 cm, 5 cm, 6 cm, 14 cm, 18 cm, then the median is 6 cm. You cross off the lowest uncrossed number, then the highest uncrossed number, and continue until you have only one or two numbers. If there is only one number left, then it is the median. If there are two, average them. The average is the median.

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
- 4
11
The variance of this data set is 22.611
Make up a data set of at least 12 numbers that have the following landmarks maxium:18 range 13 mode 7 median 12
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
