And calculator to work with grouped data and dispersed data, to calculate the mean, median, mode, percentiles, quartiles, deciles, variance, standard deviation, coefficient of variation, all accurate calculations and each with the appropriate formula.

For both cases it also executes the process of making the frequency table for grouped data and frequency table for data grouped in class intervals. Also calculating the amplitude, number of class intervals, amplitude, length of the class interval.

Similarly for both cases the respective graphs such as: the bar chart, circular sector, frequency histogram.

It also calculates the measures of central tendency, position measures and dispersion measures with their respective interpretations.
