Sort the data items into numerical order (ascending is usual, but descending can be used).
The median is the number in the middle:
If there are an odd number of items in the dataset, then the median is the middle number, which is the (n+1)/2th item (where n is the number of items in the dataset).
Otherwise there is an even number of items in the dataset and the median is the mean of the two in the middle. These items are the n/2th and the (n/2 + 1)th items.
- Put the group of values in ascending (or descending) order.
- The median is the number in the middle - or the arithmetic mean of the two numbers in the middle positions.
If there are n values, then if n is odd then m = (n+1)/2 is an integer and the median is the mth value in the ordered set.
If n is even then n/2 = m and m+1 share the middle spaces. The median is the arithmetic mean of the mth and (m+1)th values. For large values of n (>30), you can ignore this fine-tuning and simply go for the n/2th value.

What if the median has 6 values how do you work it out?
A median can have only one value.
What does median mode and range?
Median means average, and range is the range of numbers in a group. For example, the range is from 52 to 71. I don't know what a mode is.
What is the median of 23 24 26 29?
Median is the middle number in a group of numbers. If there more than one middle number, the median is either shown as average of the two numbers in the middle or shown as both the numbers. The median in 23 24 26 29 is 25 or {24;26}.
Are median and mean always similar?
No, not always. Median is the number that's in the middle of a group of numerical data. Mean is just the average of a set of numbers, which isn't always in the middle.
In math what is a landmark?
Like, it shows a stat in a graph or group of things such as: the Median, range, Mode, Max, Min, Mean.
What is the median in mathematical terms?
median is used to refer to the middle number in a group.
Are the differences between mean and median significant?
yes median is the middle number of the group and mean is the avergage number of the group put together
Which race group Which race group had the highest median income in 1999?
That was the 'human' race ... coincidentally, the only one that tracks median income.
What if the median has 6 values how do you work it out?
A median can have only one value.
What does the work median mean?
median means the number that appears in the middle
What is a sentence using the word median?
"Finding the median of a group of numbers usually isn't very challenging"
Is the median of 8 8 21 14 16 8 4?

What are median numbers?
The middle number out of a group of numbers.
What is the median in this group of numbers 20 21 22 23 24 25 27 28?
The Median is 23.5.
Who do you find the median of a group of numbers?
To find the median of a group of numbers, you would need to find the middle number of the whole group. 1 6 8 9 7 2 1 Here is the (example) group of numbers that you will find the Median in. Simply cross out numbers on each side of the set of numbers until you are left with a reamaining number. This is your Median. 1 6 8 9 7 2 1
What is the linear time median finding algorithm and how does it work?
The linear time median finding algorithm is a method used to find the median (middle value) of a set of numbers in linear time, meaning it runs in O(n) time complexity. The algorithm works by partitioning the input numbers into groups, finding the median of each group, and then recursively finding the median of the medians until the overall median is found. This approach ensures that the median is found efficiently without having to sort the entire set of numbers.
