Descriptive Statistics
Given a data set of real numbers x_{1}, x_{2}, x_{3} ... x_{N} , this calculator calculates some of the most important descriptive statistics. It sorts the data values in ascending order, determines the minimum and maximum data values in the data set and calculates the range R defined byR = maximum data value  minimum data value
It also computes the mean, median and mode and the standard deviation .
The quartiles Q1, Q2 and Q3 and the interquartile range IQR defined by
IQR = Q3  Q1
are also calculated.

Use Descriptive Statistics CalculatorEnter the data set as a list of real numbers x_{1}, x_{2}, x_{3} ... x_{N} separated by commas then press "Calculate Descriptive Statistics" and check the data entered. The outputs are:
Possible mistakes to avoid : extra space between digits, two successive commas, comma at the end of the list of the numbers entered, etc .... If you have data values separated by commas and well formated, you may copy and paste them in the text area. The text area to input data can be made much larger by pulling its bottom right hand side.
