About the Redesign

If you visited this site prior to September 15th, 2018, you've no doubt noticed that I've since launched a complete redesign of the website.

If you're not happy with the new design, I sincerely apologize. I would have preferred to keep the old desktop design, but considering the majority of my site's users are now accessing the site from small-screen, touch-enabled, mobile devices, and considering Google is now penalizing websites for not being mobile/thumb friendly, I was left with no choice but to switch to a responsive, mobile-first design.

The good news is that now that I have combined the three separate versions of the site (mobile, desktop, and ad-free member) into a single design, this will free up a ton of my time for working to make the mobile-optimized calculators more desktop/laptop friendly. In fact, some of the redesigned calculators already offer a desktop-optimized form that becomes visible when you increase the width setting of the calculator (within the "Calculator Preferences" expandable panel).

Thank you in advance for your help and patience as I work to improve the redesign.

Statistical Average Calculator

This calculator will calculate the mean, median, mode, and range of a number set. You can either enter the numbers one at a time, or paste-in a set copied from a document or spreadsheet. Plus, the results include a sorted, custom-delimited data set along with a distribution table. The Learn tab includes tutorials on:

  • How to calculate mean.
  • How to calculate median.
  • How to calculate mode.
  • How to calculate range.

Selected Data Record:

A Data Record is a set of calculator entries that are stored in your web browser's Local Storage. If a Data Record is currently selected in the "Data" tab, this line will list the name you gave to that data record. If no data record is selected, or you have no entries stored for this calculator, the line will display "None".

Data set:

Enter each element of the data set (or paste a copied data set) into this text box. Be sure each number is separated by a space, a comma, a line return, or any combination of the three. Also, if you wish to enter a frequency for each number, enter the number, followed by a lowercase x, followed by the multiplier (for 3 number twos, enter 2x3).

Average (mean):

This is the average or mean of the elements within the data set. This is calculated by summing the elements within the set, and then dividing the sum by the number of elements.



This is the median of the elements detected in the data set. If the number of elements in the set is odd, this is the middle number when sorted from smallest to largest. In the case of an even number of elements in the set, this result will be the average of the middle two numbers.



This is the smallest of the elements entered into the data set.



This is the largest of the elements entered into the data set.



This is the difference between the largest number in the data set and smallest number in the data set.



This is the mode of elements entered in the data set, which is the element(s) with the highest frequency of occurrences with the set.

If you would like to save the current entries to the secure database, tap or click on the Data tab, select "New Data Record", give the data record a name, then tap or click the Save button. To save changes to previously saved entries, simply tap the Save button. Please select and "Clear" any data records you no longer need.
