Statistics Study Lite
-- v3.14.1 June 15, 2019
(30 Statistics Functions / 42 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:
Data Table
Box-and-Whiskers Plot
Line Plot, Stem-and-Leaf Plot, Frequency Table, and Histogram
Z-Table
t-Table
Chi-Square Table
F-Table
Finding Probability with Normal Distribution
Finding t Critical Values
Finding Chi-Square Critical Values
Finding Binomial Distribution and Probability
Finding Poisson Distribution and Probability
Finding Geometric Distribution and Probability
Scatter Plot
Covariance
