It is the central number in the ordered set.
To find the median of a list of numbers, you have to put the numbers from least to greatest and then count in an equal number from each side.
For n data values, the median will be the ordinal number (n+1)/2
For even numbers of values, it is the average of the 2 middle numbers.
Example :
1 2 4 4 5 6 7 7 7 the median is 5
1 2 4 4 4 5 6 7 7 7 the median is 4.5
(4 + 5) / 2

What does the median score mean?
the number that is in the middle of that particular set of numbers.
How do you figure median?
list from least to greatest & x out outer #s until you get to the middle.What if there are TWO middle Numbers?if there are two middle numbers then add them together and divide by two to find the median
When is the average median and mode the same?
The average, median and mode of a list of numbers will be the same when the middle (or mean of the two middle numbers) is equal to the most common number in the list, and that number is also the mean. This assumes that the list has only a single mode. If you arrange such a list of numbers from least to greatest, the mode value will be grouped at the middle of the list, thus becoming the median as well. The average of the non-median values will be equal to the median/mode. Given a target mean/median/mode and a list length, you can construct an infinite number of lists that qualify. Here are some examples: 10 10 10 10 10 (or any list of only one number) 11 12 12 12 12 13 1 2 3 4 5 5 5 6 7 8 9
What is the median of the following list of numbers 4 5 7 9 10 12?
To find the median of the numbers 4, 5, 7, 9, 10, and 12, you have to list the numbers from least to greatest and then find the middle number. So if you count them out or cross 1 number from each side, (4-12, 5-10) you're left with 7-9 as middle numbers / center numbers. Because the middle numberS is 7 and 9, you have to find what's between it to find the median. And we all know between 7 and 9, there is 8. So 8 is your median.
What happens when the median has two numbers?
When the median has two numbers, you add the two together and divide by 2 . The median doesn't really have 'two numbers'; you are talking about finding the median of a set of numbers that contains an even number of numbers. The median is half-way between the two.
