To estimate the median use. The smaller the value of standard deviation the less the data in the set varies from the mean. To estimate the mean use the midpoints of the class intervals.

Next divide the sum by however many numbers you added. The median in this list is 6. For example multiplication involves addition while division also involves subtraction.

Read on to learn how to compute each value for a set of data. Add up all the numbers then divide by how many numbers there are. For instance consider the following.

If you have an even number of values in the data set put the numbers in order and find the mean of the two middle numbers in the list. So to find the median. In other words it is the sum divided by the count.

Add the 33rd and 34th numbers together and divide by 2. Mean median and mode are values that are commonly used in basic statistics and in everyday math.
