The median is the 'middle' of a set of numbers. Sort the list and find the middle number. If the set contains an even number of items, then take the middle two numbers and take the average of those two.
The median is the middle number of any given set when they are in order, least to greatest. If there is an even number of values, the median is the average of the middle two. Ex. (10, 17, 20, 45, 68) The median is 20.
Well, isn't that just a happy little problem to solve! To find the missing number when the median is given, you'll want to first list all the numbers in order. Then, if the median is the middle number, you can easily identify the missing number based on whether it falls before or after the median. Just remember, there are no mistakes in math, only happy little accidents!
Then that is the median. A median does not have to be a whole number. It can be a decimal number, even when the set of the numbers you are getting the median for are all whole numbers.
The median is the number which is in the middle of a data set when you order the set from smallest to largest. So this set is 45, 46, 90, 90, When you have an even number of numbers, you add the two middle number and divide by two So the median is 46+90 divided by 2.
