It is 85, the middle value, between 80 and 90.
Median of the set = arithmetic mean of 75 and 85 = 80
The MEDIAN is the number in the middle. In order to find the median, you have to put the values in order from lowest to highest, then find the number that is exactly in the middle. For example : 80 85 90 90 90 100 ^ since there is an even number of values, the MEDIAN is between these two, or it is 90. Notice that there is exactly the same number of values above the median as below it! Its that simple.
(80 + 90) / 2 = 85Therefore, the number between 80 and 90 is 85.
80 75 + 70 + 80 = 225 80 + 85 + 90 = 255 225 + 255 = 480 six numbers so 480 / 6 = 80
80
The median is 86.

It is 85, the middle value, between 80 and 90.
The median is 87.
Median of the set = arithmetic mean of 75 and 85 = 80
80, 81, 82, 84, 85, 86, 87, 88, 90
80, 81, 82, 84, 85, 86, 87, 88, 90
Write the data in an increasing order:40 60 79 80 90 90 98 99Since the number of data is even, the median will be the average of the two data that are in the middle (80 and 90).So the median of the data is 85, (80 + 90)/2.
