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.

Professor- 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}.
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.
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.
