Choosing a Statistical Test
Wondering what statistical test to plow through in R, SPSS, or STATA? Here's a handy decision flowchart and matching instructions for these software packages. I use it sometimes to double-check my thought process (much like I still use Andy Field's introductory SPSS textbook, dutifully marked up and full of Post-It Notes).. No matter how accomplished you might be in statistical analysis.

3) STATISTICAL ASSUMPTIONS. Statistical tests make some common assumptions about the data being tested (If these assumptions are violated then the test may not be valid: e.g. the resulting p-value may not be correct). Independence of observations: the observations/variables you include in your test should not be related(e.g. several tests from a same test subject are not independent, while.

Statistical tests are one of the tools used to assert if an input variable has a statistical effect on a resultant variable. They are also deployed to determine the difference between two or more classes. Statistical tests further assume the null hypothesis, which states that there are no differences between two populations or classes.
How to choose the right statistical test Statistical Aid
Statistical tests are used in hypothesis testing. They can be used to: determine whether a predictor variable has a statistically significant relationship with an outcome variable. estimate the difference between two or more groups. Statistical tests assume a null hypothesis of no relationship or no difference between groups.
Statistical Analysis [Which Test To Use]
As someone who needs statistical knowledge but is not a formally trained statistician, I'd find it helpful to have a flowchart (or some kind of decision tree) to help me choose the correct approach to solve a particular problem (eg. "do you need this and know that and that and consider data to be normally distributed? Use technique X.
How to select statistical procedures
The goal of this flowchart is to provide students with a quick and easy way to select the most appropriate statistical test (or to see what are the alternatives). Obviously, this flowchart is not exhaustive. There are many other tests but most of them have been omitted on purpose to keep it simple and readable.

The most important consideration in choosing a statistical test is determining what hypothesis you want to test. Or, more generally, what question are you are trying to answer. Often people have a notion about the purpose of the research they are conducting, but haven't formulated a specific hypothesis. It is possible to begin with.

When comparing more than two sets of numerical data, a multiple group comparison test such as one-way analysis of variance (ANOVA) or Kruskal-Wallis test should be used first. If they return a statistically significant p value (usually meaning p < 0.05) then only they should be followed by a post hoc test to determine between exactly which two.
