Statistics Study [for Android]

-- v3.8 Tuesday, August 16, 2016
(51 Statistics Function Buttons / 56 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, Spearmann 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 this app provides:
