This free math app is a statistical calculator with various functions:
 Statistics: You are able to calculate the mean, median, variance, maximum and minimum for a set of numbers.
 Statistical Distributions: You are able to calculate the values of different Statistical Distributions. The following distributions are available: Binomial Distribution, Normal Distribution, Students tDistribution, FDistribution, Exponential Distribution, Poisson Distribution, Chi Squared Distribution
 Frequency Table: You are able to create a frequency table for a list of numbers. Just enter the numbers, separated by comma.
Best mathematical tool for school and college! If you are a student, it will helps you to learn statistics and probability theory.
Note: Statistics is the study of the collection, organization, analysis, interpretation and presentation of data.
Probability theory is the branch of mathematics concerned with probability, the analysis of random phenomena. The central objects of probability theory are random variables, stochastic processes, and events.
Easy Statistics
The Easy Statistics is a simple application, aimed at students of raw Statistics and serves to support the proposed exercises in the classroom.
The application does not aim to do the exercises for you, but give you a result that you can compare their efforts and make corrections in their answers when necessary.

Statistics Easy is free and its maintenance is done through the income generated by advertisements within the application.

courses, or if you just need these tables!
For both Phone and 10' tablets.
These tables give you the probabilities
associated with your test statistics and
parameters.
To use these tables, just select the
distribution you want, and put in the
test statistic and parameters, and the
APP tells you the related probability.
*************************************
1) For the Normal Distribution:
Enter your Z Score, and you get
the left, right tails and the range.
2) For the Binomial Distribution:
Enter n  number of trials,
p  probability of success,
x  number of successes
and you get the probability of
x, or the cumulative probability
for x.
3) For the Poisson Distribution:
Enter the mean, and number of
occurences, and you will get
the Probability of the number
of occurences, and the cumulative
probability.
4) For the t Distribution:
Enter t and the Degrees of Freedom
and you will get the probability
of the left and right tails, and
the two tailed probability.
5) For the f Distribution:
Enter the f statistic, and the
Degrees of Freedom for the numerator
and denominator. You will get the
probability for the right tail
(alpha for the ANOVA test).
6) For the ChiSquare Distribution:
Enter ChiSquare and the Degrees of Freedom
and you will get the probability
of the right tail.
7) Inverse Normal.
Enter the probability of the
Normal Distribution left tail,
and you get the Z statistic.
8) Inverse t
Enter the probability of the
t distribution left tail, along with
the degrees of freedom, and you will
get the t statistic.
Confidence Intervals:
Sigma Known. Uses the standard
CI formula (Using Z) to determine the range with
CI% chance of containing the true mean
of the population.
Sigma unKnown. Uses the standard
CI formula (Using t) to determine the range with
CI% chance of containing the true mean
of the population.
CI for a proportion. Uses the standard
CI formula (Using p,n,Z) to determine the range with
CI% chance of containing the true mean
of the population.

 Theory and examples.
Statistical Process Control is applied in order to monitor and control a process. SPC can be applied to any process where the "conforming product" (product meeting specifications) output can be measured. Applied to Production processes as well as services, Hotels, Restaurants, Banks...
You could study the examples and try to design a method to monitor your production process or service.

Statistics Guide
Statistics Guide
We think that the Statistics Guide, resented for service by us as the Statistics World will be an understandable source for the science people and students dealing with Statistics and researchers and science people conducting surveys in different branches of science.
The statistical concepts and terms have been identified with a wide literature scan and offered to you with their explanations. Besides, the explanations of the frequently used statistical methods and the sample diameter calculations are given with examples in the application.
All of the explanations and calculation of the sample size are for information and it is recommended to be supported by a statistics expert before conducting the works.
StatisticsGlossary
In this section of the application, the definitions of the frequently used statistics terms are given. The data presented here are informative.
Sample size calculator
In the surveys to be conducted, there are various criteria to identify the number of samples. In this application, sample size calculation methods will be used using the accepted criteria when the population size is known or is not known. The sampling formula presented here are informative for the application. Technical support is recommended to be received from the statistic experts while forming the sampling plan depending on the purpose of the study.
N= Population size
The size of the population which the survey is interested.
n= Sample size
The size of the sample representing the population in order to produce data about the population in which the survey is interested.
Confidence Level
The level of confidence foreseen in the surveys.
d=Anticipated Deviation
p= Incidence/Prevalence (p=0,5allows to reach the maximum sample volume)
Statistics and Sample Size
This application is a handy tool to calculate sample size for scientific studies as well as doing basic statistics.
Thank you very much all users for all your comments and queries. Thanks to your feedback, the version of the Statistics and Sample Size app is released with a lot of improvement.
 The appearance (or interface): you can now change the app to your favorite color to make it more friendly. In this version, we have Orange, Gold, Green, Blue, Red and Grey.
 Sample size calculator: all errors/problems reported by users were fixed. An email function was also added to the Calculate button. You can now email any calculation to your friends or colleagues by press and hold the Calculate button for a while (long press/click).
 In this version, we included a new section: Random Sampling which may be helpful in randomized control trial. You can set the group name (group A, B, C... or group 1, 2, 3...) in the Preferences.
 In the Statistical Calculator, you can do statistics easier. For example, you can enter a, b, c ,d for a 2 x 2 table, calculate Chisquare statistics and obtain the p value in just a few seconds. There are more things for you to explorer, such as t test or linear regression.
 My favorite section is the Statistical Analysis from Data files. Imagine that one day your friends or colleagues email you a data file and ask you for help. What you do is to download the data file and analyze the data in just a few seconds. However, in this version the app only supports .csv file. In the near future, it will definitely support all other data file type (i.e SPSS, Stata, R, EpiData). The next version may have modeling functions. You can download the sample dataset here https://www.dropbox.com/s/s1uwk640u0z4lp0/sample_ivf.csv?dl=0
 The ads in this app is a kind of bonus for my time, but if you don't like it, just press about 20 times on the author's photo to disable ads.
Again, do not hesitate to contact me for any problem you may encounter during your time exploring the app. If you have any suggestion, please also let me know.
Thank you and have a great day.

Statistics Manually
Statistics without statistical software package?
Whether you want to (nostalgia?) or have to (cruel teaching assistant?) calculate statistics by hand, "Statistics Manually" provides you with everything you need.
It contains a large collection of formulas of statistical methods common in the social sciences as well as the statistical tables needed to interpret your test results.
These tables not just cover the "standard" z, t,chi², F and binomial distribution, but exact values for the Hartley's Fmaxtest, the MannWhitneyUtest and Wilcoxon's signed ranked test. Of course you will find the formulas of these tests as well ;)
NOTE:
To achieve best legibility all formulas are rendered on demand, hence it may take a few moments until they are displayed (especially at startup). Please excuse this inconvenience and enjoy the crisp, freely zoomable formulas.
 Reports about errors and bugs are very much appreciated
