What is the definition of median?

Answer 1

That means that, in a set of numbers, there are just as many numbers greater than the calculated median, as there are numbers less than the median.

To calculate the median, sort the numbers, then pick the number in the middle. If there are two middle numbers, take their average.

Answer 2

The middle value of a data set (group of number) when the numbers are sorted by increasing value.

i.e. If a data set has 11 values the median is the 6th value.

If there is an even number of values, the average of the middle two is the median.

i.e. 1 4 6 10 12 16

The middle two values are 6 & 10 so the median is 8.
Take all the scores in a set of data and put them in order. If the number of scores is odd, then the one right in the middle is the median. It separates the scores into two equal 'piles'. If the number of scores is even, and the two middle-most values are different, usually the half-way point between them is chosen as the median, by convention. If they are the same, that is the median. it is like the average of something

e.g. 1, 5, 5, 6, 8.

MAKE SURE THEY ARE IN ORDER! Cross of one from the left and then one from the right and keep going until you get a number in the middle like so. the answer here is 5.

e.g. 7 9, 11, 15, 25*, 28, 30, 31.

If you get 2 answers like here* then you need to find the difference between the numbers. The calculation you would do here is 25 - 15 = 10 then, 10 divided by 2 = 5. then, 15 + 5 = 20.
Meadian=Middle.

4 ex: 1,4,7,9,15,17,23

the meadian is 9, because its in the middle of all those numbers :)

i hope this helped. i just took a yest on it in school today.
