Best Answer

It is 80.5, the number halfway between them.

Median means "half of the numbers are above and half are below". With only two numbers we just split the difference.

In this case the Median and the Mean are the same number - but this is not always the case.

If our numbers were 80, 80, 81, 83, the Median would still be 80.5 but the Mean would be 81.

median is 79. Write in order; median is middle number: {72, 89, 67, 81, 75, 79, 81, 80, 62, 64, 83} → {62, 64, 67, 72, 75, 79, 80, 81, 81, 83, 89} To find middle number, count the number of data items, add 1 and divide by 2. If this is a whole number, that is the data item which is the median; if it is a fraction, take the mean average of the data items of the positions either side of the fraction (eg if the fraction is 3.5, take the mean average of the 3rd and 4th data items) There are 11 data items → median is (11+1)/2 = 6th data item → median is 79
