### Statistical Tables and Formulae

This web page lists statistics formulas used in the Stat Trek tutorials. Each formula links to a web page that explains how to use the formula. Unless otherwise noted, these formulas assume simple random sampling. In the following formulas, X and Y are random variables, and a and b are constants. The correct formula for degrees of freedom DF depends on the situation the nature of the test statistic, the number of samples, underlying assumptions, etc. Below, the first two formulas find the smallest sample sizes required to achieve a fixed margin of error, using simple random sampling.

The third formula assigns sample to strata, based on a proportionate design. The fourth formula, Neyman allocation, uses stratified sampling to minimize variance, given a fixed sample size. And the last formula, optimum allocation, uses stratified sampling to minimize variance, given a fixed budget.

You can enrol yourself, without a password, and resources are arranged in sections to help you find those which are useful to you. The University of Bath formula book is used in some exams.

Hi Charles, At the table above should the critical value be changed for a one or two-tailed test? Thank you. Jose, I believe that the table is for a two-tailed test. I am examining whether two sets of samples are drawn from the same population, neither is expected to have a normal distribution. I set everything up to do the Two-sample KS test, which worked fine — but then realised that since one sample has a few hundred samples n and the other has tens of thousands m , my Dmn is always going to be a tiny number and the null hypothesis is uniformly rejected. Jay, You might consider using the Two-sample Anderson-Darling test, although it may have the same problem.

Perform the requested conversions. Set n to 4 for quartiles the default. There are number of ways available to cheat or hack the MyMathLab system, but it is worth noting that a number of the problems have already been resolved by the MyMathLab team. We call it the sample space and indicate it by S. Statistics Solutions is a dissertation editing service with expertise in every aspect of the dissertation from both a quantitative and qualitative approach. So, there are 12 face cards in the deck of 52 playing cards. Hint: Drawing a tree diagram with the probabilities will help answer these questions a.

### Statistics Formulas

In probability and statistics , Student's t -distribution or simply the t -distribution is any member of a family of continuous probability distributions that arise when estimating the mean of a normally-distributed population in situations where the sample size is small and the population's standard deviation is unknown. The t -distribution plays a role in a number of widely used statistical analyses, including Student's t -test for assessing the statistical significance of the difference between two sample means, the construction of confidence intervals for the difference between two population means, and in linear regression analysis. The Student's t -distribution also arises in the Bayesian analysis of data from a normal family.

Excel provides formulas for most of the common tests and distributions as described in Built-in Statistical Functions. For these we use statistical table, as described in this appendix. See Supplemental Functions for a list of the various Real Statistics functions which can be used for the lookup of values in these tables. I plan to release a book in a couple of month which will contain the statistics tables. You will be able to get the book as a pdf. Hi charles, I am still waiting for the book that contain the statistics tables.

It seems that you're in Germany. We have a dedicated site for Germany. Authors: Kokoska , Stephen, Nevison , Chris. All students and professionals in statistics should refer to this volume as it is a handy reference source for statistical formulas and information on basic probability distributions. It contains carefully designed and well laid out tables for standard statistical distributions including Binomial, Poisson, Normal, and Chi-squared. In addition, there are several tables of Critical Values for various statistics tests.
