Enter a list of numbers separated by blank-spaces or commas.
To calculate the statistical mean of the list of numbers,
press Enter or Return on your keyboard or keypad, or click the button entitled "Mean".
Each number in the input list should be in one of the following formats.
You can mix the formats:
Integer231457Decimal2.71828+9862.314Scientific Notation2.7E+20.3528e03Example Input Lists2, 2.7E+2, 2.718, 0.35e03 ...2 2.7E+2 2.718 0.35e03 ...Maximum Input Length
You can enter a maximum of 5-million characters, including numbers,
commas between numbers, and blanks spaces.
Statistical Mean (Statistical Average)
This output field displays the statistical mean (statistical average), of the list of input numbers.
Number of Data Samples
Displays the number of data samples that where used to calculate the statistical mean.
The number of data samples displayed, should coincide exactly with the length of the input list.
Calculator Memory
You can save the result of this output field in the Calculator Memory,
then use the saved result as input for other converters and calculators anywhere on the website.
To save this result, click inside the output field,
and then click the button entitled "Save" in the Calculator Memory.
See the Calculator Memory for more details.
TIP:Precision of the calculator is 15 significant digits, from left to right. Digits after the 15 left-most digits, are not significant.
Numeric Range of the calculator is:
+1.797e+308 ... -1.797e+308+1.000e-311 ... -1.000e-311
Number of Data Samples
This output field displays the number of data samples that where processed for the statistical analysis.
The number of data samples displayed should coincide exactly with the length of your input list.
If it does not coincide, it is because your input list contained blank elements, such as:
1, 2, , 4, 5, 6Calculator Memory

The Control Buttons
The statistical mean calculator has three control buttons.
Button Entitled "Decimal"
In this mode the converter will produce results in Decimal format whenever possible, like so:
-9999.10.0005987
However, the converter will automatically produce results in Scientific Notation
when the results cannot be shown properly in Decimal format.
Button Entitled "Scientific"
In this mode the converter will always produce results in Scientific Notation, like so:
-9.9991e35.987e-4Button Entitled "Mean"
Calculate the statistical mean of your data list, by using any of these methods:
Click the button entitled "Mean"
Click the button entitled "Decimal"
Click the button entitled "Scientific"
Press Enter or Return on keyboard
TIP:
Scientific notation is better for visualizing and working with big and small numbers, compared to decimal format.
Computes the statistical average of a list of input data, the population standard deviation, the sample standard deviation, the population variance, and the sample variance
Computes the linear regression of a list of input data, graphs the input data on a scatter plot, graphs the linear regression line, and displays the linear regression alpha and beta
