What if the data set has a even amount of numbers and the median was between the same numbers?

The median of a set of data is the "middle" value. Whenever there is an even number of values in a data set, you take the middle two numbers, add them together, and divide by two. For cases when the two middle numbers happen to be the same, you still add them up and divide by two. The key point is just that the answer will be the same as both the numbers.

How is it possible for two sets of data to consist of different numbers but have the same mean the same median the same mode?
The range of a data set is the difference between the largest and smallest number in your set of data. Median is the number that comes in the middle. 54, 55, 56 has a range of 54-56 and a median of 55. The set 53, 55, 57 has a median of 55 also!
What is median in the set of data?
The median in a set of data, would be the middle item of the data string... such as: 1,2,3,4,5,6,7 the Median of this set of data would be: 4
What is the median for the set of data for 45 58 19 68 13 44 39?
Once you put the numbers in order, the median is the middle number or the average of the 2 middle numbers. 13, 19, 39, 44, 45, 58, 68. 44 is the number in the middle, so 44 is the median.
Can a mean average ever be higher than a median average?
Yes. If the predominant data are higher than the median, the mean average will be higher than the median average. For example, the median average of the numbers one through ten is five. The mean average is five and one-half.
What is the definition of median in math?
the median is the middle number in a set of data.
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.
Is it true that the median is always one of the data points in a set of data?
No, it is not necessarily true that the median is always one of the data points in a set of data. The median is found by arranging the data in numerical order and selecting the middle value. This value might be one of the data points, but it could also be the average of two data points if there is an even number of values in the set.
Why is the median not always in the data set?
The median is the middle number of a set. If the amount of numbers is even and the two middle numbers are not the same, then the value half way between them is the median. It is also the value when you add those two numbers and divide by 2. So if your two middle numbers were 7 and 5, the number halfway between them is 6, as is the number when you add 7 and 5 and divide by 2.
How do you find the median of a even data?
Take the number in between the middle two numbers. Like 32, 34. The median would be 33
What is the median number between 16 and 25?
The median of a set of numbers is the middle number when the numbers are listed in numerical order. When there are an even number of data items in the set, then the median is the mean average of the middle two numbers. In the set {16, 25} there are two data items, so the median is the mean average of the middle two (which for a set of 2 is both the numbers) → median = (16 + 25) ÷ 2 = 20.5
Does the median in the set of data have to be close in value to the mean?
The median of the set of data does not have to be close in value to the mean. First of all, what is the median? The median is the middle number between a set of numbers. So if you are asked what the median of a set of numbers is.... put the set of numbers in order from lowest in value to highest value. Example.... 1, 2, 3, 45, 100, 1010, 1020. In this example, what is the median, or the middle number? It's ... 45! If you want to find the mean ... add all of the numbers and divide the sum by the AMOUNT of numbers there are in the set.... the sum of the set is 2181.. and there are 7 numbers in the set. The mean is 2181 / 7 = 311. 57. You can see that 311 is not close in value to 45.
What if the data set was even and the numbers were the same for the median?
You then add the two middle ones and divide by two to get the median. If the numbers are the same then that is your median.
Are the mean median and mode always numbers from a list of data?
the median and mode are but the mean is not
Why the median of a set of data does not have to be one of the numbers in the set of data?
Because, if there is an even number of results in the set of data, the mean must be calculated by finding the half-way point between the two central numbers.
What is mean and median?
mean~ all the numbers in the data added together divided by the number of data. The mean is the same as the average. median~ the exact middle of the set of data. Example: 1,1,2,2, the median is 1.5 mean- the average median- the middle number in a set of numbers in a group.Example of Median-1,3,5,7,9,4,5 (put them in order and list them from least to greatest)1,3,4,5,5,7,9the median is 5!

What do you do when the median is two numbers?
For an even number of values, there will be 2 middle numbers. Take the average of the 2 middle numbers for the median. It will be a value not in the data set.
