**Give two methods to find mean, mode and median of given data.**

To find out mean median and mode of a list of sample data, the list may be created in two ways in Geogebra, namely, using input bar or the spreadsheet view.

Method 1 : In the input field of the input bar, type the sample data as a comma delimited list with in braces (Curly brackets). It may be named using lower or upper case letters. If no names are given, the program names them as list1, list2 etc. The Algebra View displays the list and its name under free objects.

Method 2: Enable the spreadsheet View from the View menu. Enter the data in the first column or row. Select all data by dragging the mouse and select Create List from the right- click context menu. The algebra view displays the list and its name.(L1, L2, etc) under dependent objects.

Suppose a list has been created with a name L1. To find the mean, median and mode of the list, type each command with the list name enclosed within square brackets in the input bar, Mean [L1],Median [L1], Mode [L1] and press enter key. The algebra view displays the values under dependent objects.
