What is the median of the following data 9 15 17 18 6 20 8 5 18 18 10 5 14 12 10 7?
First, to find median put numbers in order so: 5, 5, 6, 7, 8, 9, 10, ( 10, 12 ,) 14, 15, 17, 18, 18, 18, 20 10 + 12= 22 divided by 2= 11, the median is 11
What is the median of 4 6 7 9 10 12 14 15 15?
The median is the central value, 10.
What is the median of 5 6 8 9 10 10 11 12 13 14 15 18 19 20 and 22?
12

How do you find the mean mode and median from frequency tables?
"mean" is the "average" in normal terms. Add the terms, and divide by the number of terms. "mode" is simply the most common value. If there are more 3s in the list than any other number, 3 is the mode. The "median" is the most complicated of the three terms. When you put the list in order, the median is the number that has the same number of terms less than it as above. If there are an even number of terms, you need to find the two in the middle and take the mean of their values. example: {14, 10, 11, 6, 5, 15, 1, 15, 16} mean: 93 / 9 = 10.333◄ mode: 15 because there are 2 of them and only one of any other.◄ median: Put them in order: {1 5 6 10 11 14 15 15 16} 11 is the middle term, so is the median. If you were to include another 14, then the list is {1 5 6 10 11 14 14 15 15 16}, so 11 and 14 are in the middle with 4 above them and 4 below them, so the median would be (11+14)/2 = 12.5◄ ■
