15 - it has 3 numbers either side of it.
It is 9, the middle number when they are listed in order.
Yes. In the set (9, 10, 11, 12, 13) 11 is the median and the mean.
Mean = 14 Median = 12 Mode = 12
13
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

It is 9, the middle number when they are listed in order.
The are 11, 17 and 24.
Yes. In the set (9, 10, 11, 12, 13) 11 is the median and the mean.
mean = 19 median = 12 mode = 12
Mean = 14 Median = 12 Mode = 12
13
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
Arrange the numbers in ascending order: 7 9 9 12 13 15 16 and the middle number is the median which is 12
11 13 15 18 20 20 The median is the middle number when they are in numerical order, so the median is 16.5. It is 16.5 because there is an even number of integers so you find the middle of 15 and 18
median of {5, 15, 9, 13} is 11 To find the median of a dataset sort the data into order and the median is the middle one; if there are an even number of items in the dataset, then the median is the mean average of the middle two. {5, 15, 9, 13} → {5, 9, 13, 15} There are 4 data items, → median is mean of {9, 13} = (9 + 13) / 2 = 11.
