Fairmont State University Library: PSYC Resources for Behavioral Statistics, Research Methods, and Capstone: Choosing and Running Basic Analyses

WHICH STATISTICAL TEST SHOULD I RUN?

NOTE: This LibGuide links to many external sources and will be updated as more resources are identified. Please report any broken links to zmoore@fairmontstate.edu.

Page Info

The top box on this page contains a series of resources to help you identify the appropriate statistical analyses to run, based on the types of variables that are measured or manipulated in your study. (For a review of variable identification, see the tab in this LibGuide).

The other content boxes on this page contain links to SPSS tutorials for running descriptive, correlational, and experimental analyses; as well as links to online statistical tables and calculators for small data sets.

Interactive Flowchart for Choosing the Appropriate Test Follow this link to figure out an appropriate statistical test by answering a few questions about the variables.
