Statistics and Probability

As of version 4.0, there are tools in GeoGebra that lets you examine statistical data and probability distribution functions in a very easy way.

An explanation on how to handle frequency tables and bar charts can be found on the page Statistics - Bar Charts.

Statistical analysis

If you have grouped data (as in columns A-E) or one single list of data (as in column G), you can use GeoGebra's tools for analysing statistics.

In order to use the tool "One Variable Analysis", you first select one or several columns in the spreadsheet.

If you choose to show the data, you can uncheck some values to examine how all statistic changes.

Image

Generate random data

There are a number of commands for generating random numbers.

Image

If you for instance write the code RandomNormal[20,5] in cell A1, you can make as many relative copies as you need. They will all be randomly generated and normally distributed.

Image

Examine probability distribution functions

By using the tool "Probability calculator" Image, you will get all possible data regarding probability distribution functions.

Image

You can change the boundaries by dragging the arrows and you can enter numbers in any box. All values change dynamically.
