App Profile: StatsLab: Statistics Calculators

+Fun Fact: StatsLab is written and maintained by a real-life Stats Professor...

StatsLab is the best companion to your statistics course. It includes fast and accurate probability calculators as well as statistics calculators.

Statistics doesn't have to be about tedious and time consuming calculations. Let StatsLab handle all the number crunching so you can do important things like make decisions!

With StatsLab you can quickly compute probabilities, inverse probabilities, simulate experiments, perform data analysis, generate random numbers, do a chi-square test of independence using contingency tables and ANOVA (analysis of variance) tests. We are constantly adding new modules and features. Follow us on twitter @StatsLabApp.

There are currently 6 modules with plans to add even more.

> Data Analysis
Enter your own data set and get summary info including mean, median, mode, standard deviation, variance, quartile numbers, box-plot, frequency and relative frequency tables and histograms and much much more.

> Probability Distributions
Normal Distribution

Chi-Square Distribution*
F-Ratio Distribution*
Binomial Distribution*
Poisson Distribution*

> Simulate Experiments
Dice Rolls (Up to 6 dice and up to 2000 rolls!)*
Toss Coins (Up to 10 coins and up to 2000 tosses!)*
