In this mode the left column of buttons is allocated to statistical functions:

Most of the functionality in this mode is centered around the button. To create a data list of numbers, enter a number into the calculator and press . A sequentially increasing number is shown on the display indicating which position in the Data “list” the number occupies. A traditional calculator only stores three values for statistical functions: The number of discrete items in a list, the sum of the data items entered and the sum of the square of all data items in the list. KCalc differs by actually storing each discrete value, allowing you to calculate the median value of the data.
