Whatever you like. The median value for each of the following three sets is 10. For the set {1, 9, 11, 12}. the mean is 8.25, smaller than the median. For the set {1, 9, 15, 15}. the mean is 10, the same as the median. For the set {1, 9, 15, 16}. the mean is 10.25, larger than the median.

The median is 15.

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.

Mean: 11 Median: 11 Mode: 4 Range: 18

It is 12, the middle number.

The median of a set of numbers is the middle number when the numbers are listed in numerical order. When there are an even number of data items in the set, then the median is the mean average of the middle two numbers. In the set {16, 25} there are two data items, so the median is the mean average of the middle two (which for a set of 2 is both the numbers) → median = (16 + 25) ÷ 2 = 20.5

One possibility: 5, 6, 7, 7, 7, 12, 12, 13, 14, 15, 16, 18

So first let's order the set: 4,8,12,12,15,16 The mode is 12, there are 2 of them and 1 of everything else. The median is also 12 and the mean is (4+8+12+12+15+16)/6

The mean of the numbers is 22. The median of the numbers is 21. The mode is 16, 20 and 30 or you can say the set has no mode.

The median is 15.

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.

Mean: 11 Median: 11 Mode: 4 Range: 18

It is 12, the middle number.

12, 14, 15, 16, 16, 17 The median is 15.5 The mode is 16 The range is 5 The mean is 15

When the numbers are placed in numerical order, it is the number in the centre of that list. e.g. 18, 4, 6, 12, 9, 16, 5, 7, 12, 2 Goes to... 2, 4, 5, 6, 7, 9, 12, 12, 16, 18 So the median is........... ^ (Halfway between 9 and 12, 10.5)
