Statistics Study
-- v4.25.1 June 15, 2019
(72 Statistics Function Buttons / 74 Statistics Study Notes)
Statistics Study provides 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, frequency table, Pearson correlation, Spearman correlation and covariance.
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 of functions this app provides:
