Mean Calculator

Mean calculator 

Find the mean of a discrete data set and know the different properties of the data using this calculator.

For instance, the mean calculator along with giving the mean with a step-by-step solution gives the total number of data, sorted array, and smallest and largest data values.

What is the mean of a data set?

One word to describe the mean is “average value”. A value that lies between both extremes of the data. 

There are other types of means like harmonic and geometric but the basis of it all or the “Actual mean” is the arithmetic mean.  

Mean formula:

Small X bar is the notation used for mean in mathematics although it is represented differently in statistics. N is the number of data set values. Sigma notation means summation.

How to calculate the mean?

Find the summation of the whole data. Count how many values are present in the data. Divide the summation by that number. The answer is the mean of the data.

Alternatively, use the mean calculator.

Example:

Find the mean of the following data set:

10, 10, 34, 23, 54, 9, 10, 2, 38, 23, 38, 23, 21

Solution:   

Step 1: Add the data.

= 2+9+10+10+10+21+23+23+23+34+38+38+54

= 295

Step 2: Count the values.

There are a total of 13 values.

Step 3: Divide the sum by 13.

= 295/13

= 22.692
