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 compute mean and median?
The mean is when you add all the numbers together and divide by how many numbers there are, and yes zero does count. The median is when you put all the numbers together and whichever one is in the exact middle is the median. Sometimes there is an even amount of numbers. If there is you find the middle of those two 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.
What is the difference between finding the median for odd numbers or even numbers?
Median is finding the center of a line of some values. The values have to list in ascending order. When there are an odd amount of numbers: the median is the middle number. Example: find the Median of {12, 3, 5}. Put them in order: {3, 5, 12}. The middle number is 5, so the median is 5. When there are an even amount of numbers: There will be two numbers in the middle; the median in this case is the mean (average) of these two. Example: find the Median of {3, 5, 7, 12, 13, 14, 21, 23, 23, 23, 23, 29, 40, 56}. There are now 14 numbers and so we have a pair of middle numbers and the middle numbers are 21 and 23. To find median: (21 + 23) ÷ 2 = 22. So the Median in this example is 22.
How do you find the median when the amount of numbers is even?
You calculate the arithmetic mean of the two middle numbers. For example, to find the median of {1, 7, 4, 2, 5, 8} the middle two numbers of the ordered set are 4 and 5, whose average is (4+5)/2 = 4.5. So the median is 4.5
What happens to the median when you come up with two answer?
when you have an even amount of numbers while trying to find the median, you first find the two numbers that are at the median and then take all the numbers between them and find the median of that. if that amount of digits is also even, then you must have a decimal median.
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 find the median if there are an even number of entries?
If you have to find a median in a set of numbers in which there are an even number of entries, you must find the average of the two numbers the come in the middle.

What is the median of 74 75 80 85 How do you find it?
The median is the middle number of a set of numbers when they are arranged in order. If there is an odd amount of numbers, you take the middle number. If there are an even amount of numbers, as in this case, you take the number halfway between the two middle numbers. The two middle numbers are 75 and 80, so halfway between that is 77.5 which is the median.

What is the median of 50 54 62 53 53 61?
The median of a set of numbers is the middle number when they are laid out in numerical order. When there is an even amount of numbers in the sequence like this one, there are two numbers in the middle. To find out the median from these two numbers, you just need to find the average of the two numbers. As the two numbers in the middle of this set of numbers is 53 and 54, the average is 53.5. This means that the median of this set of numbers is 53.5.
How do you find the median when the amount of numbers is even?
You calculate the arithmetic mean of the two middle numbers. For example, to find the median of {1, 7, 4, 2, 5, 8} the middle two numbers of the ordered set are 4 and 5, whose average is (4+5)/2 = 4.5. So the median is 4.5
What is the median of a set of numbers if the set of numbers is even?
To find the median of a set of values with an even number of values, place the values in ascending or descending order, find the 2 middle numbers and add them together and divide that total by 2 and that's 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 does median means on a calculator?
The median of a set of numbers in the number that is exactly center. For example, if 1,2,3,4,5,6,&7 were a set of numbers that you were asked to find the median of, 4 would be the correct answer. To find the median, one must order the number from least to greatest and cross out all the numbers until you find the center. In such case that you are asked to find the median in a set of number that has a even amount such as 1,2,3,&4, one would have to add together 2 an 3 then divide the product by 2.
