How do you find the median in a even amount of numbers?
After ordering the numbers from least to greatest, average the two middle numbers.
Can a set of data always have a median?
Yes, it can. Even if you have an uneven amount of numbers you can find the median by taking to two middle numbers, adding them together and then dividing by 2.
How do you find the meadian in a set of numbers?
Order the set from least to greatest. The number in the middle, or the mean of the two numbers in the middle, is the median. That is, if S is the set, then for #S = 2n - 1, Sn is the median, while for #S = 2n, (Sn-1 + Sn)/2 is the median.
How do you find the median of an even set of number?
Find the average. That is, add all of the even numbers together, then divide that by the number of even numbers.
What do you do if you can't find the median in a set of numbers?
Every set of numbers has a median, so it can always be got. It is the middle value when they are arranged in numerical order. If there is an odd amount of numbers, then it is in the set, as there is one definite middle number. If there are an even amount of numbers, then you take the two middle numbers and find the value that is half way between them if they are different. You can also add the two numbers and divide by 2, which will also give you the median.
