Mean: 17 Median: 19 Mode: 20

In the example provided, the quartiles are: 25% = 16.5 (the median of {15, 16, 17, 18}) 50% = 18.5 (the median of {15, 16, 17, 18, 19, 20, 21, 22}) 75% = 20.5 (the median of (19, 20, 21, 22})

16.5 is the median.

17

Mean = (11 + 14 + 20)/3 = 45/3 = 15 Median = 14 Mode = 11, 14 and 20 (these values appear once, others do not appear even once!)

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

Mean: 17 Median: 19 Mode: 20

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

The median is 19.

Mean: 19 and 1/6 Median: 20 There is no mode.
