Standard Deviation Calculator

This calculator is used to determine the population standard deviation and the variances. It is an effective calculator that has a single text field and two control buttons that perform different functions of the calculator. The first step is to enter the data values in the blank text field using commas or spaces. For example, you can enter a data with the values 45, 56, 78, 98, 122 or 45 56 78 98 122. Confirm that you have entered the values correctly before you click the ‘Calculate’ button. It is used to execute the conversions of the numbers entered in the text field.

This calculator performs multiple conversions at once making it efficient and reliable. You will get your results in form of Population standard deviation, Sample standard deviation, Population variance, Sample variance and the mean. The ‘Reset button is active and is used to clear all the previous calculations from the text fields.

For example
Determine the population variance and standard deviation of the following data; 20, 30, 40, 50, 60.

You should choose to enter the values either with commas or spaces. Click on the ‘Calculate’ button. The results will be displayed as;

Population Standard deviation = 14.142135624

Sample standard deviation = 15.811388301

Population variance = 200

Sample variance = 250

Mean = 40

The Discrete random variable standard deviation is calculated using the probability and data number or weight. This calculator has two columns where you will enter the values of the probability and data respectively. Click on the ‘Calculate’ button to perform the calculation. If you want to carry out new calculations, use the ‘Reset’ button to clear all the text fields. The ‘Add row’ control is useful in adding multiple rows when performing calculations with several values. The results will be displayed below the three controls. You can determine the standard deviation, variance and mean.
