Statistics Study Lite

-- v3.27 October 13, 2025

(38 Statistics Functions / 112 Statistics Study Notes)

Statistics Lite provides basic descriptive statistics such as sum, sum of square, mean, sum of squared deviation, variance, standard deviation, median, mode, momentum, skewness, kurtosis, box-and-whisker plot, and frequency table,

It also provides various statistical tables such as z-table, t-table, Chi-square table and F-table.

Using this app you can find various critical values from z-distribution, t-distribution, Chi-square distribution and F-distribution. You can also compute probability from binomial distribution and Poisson distribution.

The following is the list this app provides:
