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

mean = 19 median = 12 mode = 12
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
the median is the number in the middle when arranged in numerical order. 11 12 18 21 24 24 . There is no one number in the middle so take the two middle numbers and average; 18 + 21 divided by 2 = 19 and 1/2
