18.5 As there are an even number of numbers, the median is the mean of the middle two; in this case median is (18 + 19)/2 = 18.5
18
12,13,13,15,17,19,23 15 is the median of these set of numbers
mean = 19.833... median = 19.5 mode = 19
15
The mean is 19. The median is 18. There is no mode.
The median is 19.
18.5 As there are an even number of numbers, the median is the mean of the middle two; in this case median is (18 + 19)/2 = 18.5

12,13,13,15,17,19,23 15 is the median of these set of numbers
mean = 19.833... median = 19.5 mode = 19
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.
The median of {10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20] is the 6th values which is 15.
There are infinitely many sets. One possibility is {18, 18, 18, 18, 18, 18}. Another is {15, 16, 17, 19, 20, 21} or {-5000, -4999, -4998, 5034, 5036, 1,000,000,000,000,000}
They are 15, 16, 17, 18 & 19.
