About STA: Statistical Toolbox
TOOL FOR STATISTICS AND PROBABILITY THEORY.
---------------------------
Features
---------------------------
- Distribution tool
- Statistical tests
- Descriptives
Besides these areas, the application supports saving, loading, and deleting datasets where applicable.
---------------------------
Distribution tool
---------------------------
The distribution tool offers the following features: plot the pdf/pmf, properties (like mean value, variance, and support), cumulative probability, point mass/density, quantiles, and generating/sampling from the distribution.
Discrete probability distributions: Binomial, Hypergeometric, Negative binomial (or Pascal as it is also called), Poisson, uniform, and Zipf
Continuous probability distributions: Beta, Cauchy, Chi^2 (Chi squarred), Exponential, F (or Fisher-Snedecor as it is also called), Gamma, Normal (or Gaussian as it is also called), Student's t, uniform, and Weibull
---------------------------
Statistical tests
---------------------------
- One way ANOVA
- Chi^2 tests: Pearson's Chi^2 test for independence and observed vs expected counts
- Correlation tests: Pearson's correlation and Spearman's correlation
- Student's t-tests: One sample and two sample (both homoscedastic and heteroscedastic are supported)
---------------------------
Descriptives
---------------------------
- Plot a histogram
- Summary statistics as: number of observations, min, max, mean, standard deviation, variance, median, skewness, and kurtosis

The best so far. I use SPSS. I cross checked my hypothesis test with this software. The results are accurate. It is more or less a hand calculator for advanced statistics.

Brings up a keyboard that only allow one number to be entered - no space or comma key.

Very unwieldy because, with TouchPal keyboard, have to manually go back to numbers after every entry. Fix this and it looks good.

There are some very practical application of statistics. Regression is central application.

I teach statistics at the college level and just found this app. Although listed as for phones, it worked very well on my Samsung Tab Pro 12.2. Highly recommended

I am teaching Statistics and this app is very good! I suggest the author to include four tools: 1 - A nonparametric ANOVA test (Kruskal-Wallis). 2 - The Standard Error of Mean. 3 - Histograms and. 4 - Boxplots (Mean +- Standard Error of Mean).

Awesome app! Like having all the stats tables in my pocket. UI could use a little more polish.

Awesome! Can't believe it's free! Development wish list would be to include Weibull B10 calls for reliability, but I still use this a lot.

Great for binomial distribution probability problems. Edit: is there a way to find variance for uniform probability distribution?

Very useful. I wish it had a number pad for data entry. Thanks!

It comes handy when teaching probability distributions or SMG quick double checks on what version distribution should look like or how its parameter should be interpreted. I love it.
