Statistical Tables Plus 4.1 Details
Statistical Tables Plus Version 4.1 Value packed combination of Probability Distribution Tables, plus commonly used statistical inference tests. Updated UI. Added Permutations, Combinations and Sample Sizes. Convenient, Accurate, Easy to Read electronic Probability Distribution Tables. Commonly used statistical inference tests. Confidence Interval calculation. Normal, Binomial, Poisson, T, F and Chi-Square Distributions. Also, invNorm and invT calculations. Data entry for 10 variables. Descriptive Statistics. Statistical Tests Including t-test, ANOVA, MannWhitneyU Test, Chi-Square Test, Simple Linear Regression. Now contains calculators for Confidence Intervals (Sigma Known, Sigma Unknown, Proportion). Great for Intro Probability Statistics 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 Chi-Square Distribution: Enter Chi-Square 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. Statistical Utilities: Permutations and Combinations give number of ways to select n Items out of N Items. In Permutations Order of selected Items matters, in Combinations it does not. Sampling is without replacement. Sample size n, is number needed for CI with following parameters: alpha - CI between 0 and 1.0 sigma - Known standard deviation. E - desired error. Formula is: n = (Z^2 * s^2) / E^2 Z is Z score for (1-alpha)/2 Includes 5 common statistical tests, and Descriptive Statistics. Help for each test is included in the APP. Free!. Please visit this APP in the Google Play store to Rate and enter comments. This will help us improve the APP over time. Due care has been taken for accurate results. This APP is for educational use. However, no warrenty against any damages due to use is included or implied.
