25.5 is the median.
16.5 is the median.
min= 12 max=21 median=17 mode=17 mean=191
22
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.
min= 12 max=21 median=17 mode=17 mean=191
16
mean = 19 median = 12 mode = 12
22
Mean: 19 and 1/6 Median: 20 There is no mode.
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})
all you do is this example 12 19 20 21 45 before you do it put it in order then cross out side by side like you would cross out 12 and 45 then 19 and 21 then your median would be 20
18
Order them: 15 16 17 21 21 Find the middle one: 17 That is the median
19
To find the median, first arrange the numbers in order (which they already are). Since there are 10 numbers (an even set), the median is the average of the two middle numbers. The two middle numbers are 16 and 17, so the median is (16 + 17) / 2 = 16.5.
