VERY incomplete app. (1) We need more distributions. (2) In normal distribution (and others), we need a way to compute X given the percentile and the mean and the standard deviation. (3) We need also for the normal distribution (X, miu, sigma), not only for the normal standard distribution (Z), to compute percentiles.

Works as intended but... Stock hp prime software has more. Functionality. Wolfram alpha works better actually

Statistics 1
$0.99 for a limited time!
Coming Soon to the Android version  Quizzes & Calculators
Intro Statistics ETextbook with: lessons, flashcards, decision trees, a glossary, and a list of formulas and symbols.
It's the perfect tool for students in an intro statistics course, or professionals who need a Stats 101 book on their phone.
Statistics 1 was pilot tested in a statistics course at Abilene Christian University. Here’s what some of the students had to say:
“It gives reallife examples in each lesson and tables so I can easily reinforce the information I just read.”
“It's a great tool to go to for an easy answer. Instead of searching through a whole textbook I can click on a specific section in the app and find the answer easily and see a graph that represents the idea.”
Coming soon: Quizzes, calculators, and sims.
The app was designed by educational psychology Ph.D.s, statistics teachers, and software experts. Many of us learned stats the traditional, boring way – through books and lectures. We always wanted more interactive, visual, and engaging ways to learn stats. Stats has many abstract concepts so we use realworld examples to anchor your understanding.

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.

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.
