The median is 15.

The median of {10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20] is the 6th values which is 15.

6, 10, 11, 12, 14, 14, 15, 22 mean: 13 median: 13 mode: 14 range: 16

It is 15.

First put them in numerical order,12, 13, 13, 15, 15, 18.since there is an even set of numbers the median is the mean of the two middle numbers12, 13, 13, 15, 15, 18.(13+15)/2=14

15

14

12,13,13,15,17,19,23 15 is the median of these set of numbers

Median = 15

Arrange the numbers in ascending order: 7 9 9 12 13 15 16 and the middle number is the median which is 12

12

The median is the central value, 10.

15*14*13*12 = 32,76015*14*13*12 = 32,76015*14*13*12 = 32,76015*14*13*12 = 32,760

The average mean is: (11+12+13+14+15)/5 = 13

14. Put in order: {1, 6, 10, 12, 12, 13, 15, 19, 27, 31, 32, 40} There are 12 data items, so the median is the (12 + 1) ÷ 2 = 61/2th data item. As 61/2 is not a whole number, take the mean average of the 6th and 7th data items: 6th is 13, 7th is 15 ⇒ median = (13 + 15) ÷ 2 = 14

Any multiple of 5460 is a common multiple of 12, 13, 14 and 15.

1 is a common factor of 11, 12, 13, 14 and 15.

The numbers 12, 13, 14 and 15 are spelled twelve, thirteen, fourteen and fifteen.

13 - if there is no "middle" number then you take the average of the 2 either side of where the middle would have lain.

3-3-3-9-9-11-12-14-15-15-2311 is the median

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

14, which is the middle number when they are listed in order.

The answer is 8.5
