Statistics Guides

A lesson teaches one idea. A guide takes you through one complete task, from the file you were given to the paragraph you hand in. These seven are long, and they are written for when something is due and the concepts you need are spread across several lessons.

Each guide is self-contained. When a step needs a concept, it links to the lesson that teaches it, so you can go as deep as you have time for. Five of the seven use a file from the practice datasets, so you can reproduce every number on your own computer.

The seven guides

Choosing Statistics for Your Dissertation Three questions, answered in order, that point to the right test. Plus advice on the messy designs that flowcharts leave out. Clean Your Survey Data, Step by Step Raw questionnaire export to analysis-ready file in eight steps: validation, missing data, reverse-coding, composites, reliability. Analyze Your Thesis Data in JASP Every step in free, point-and-click software: open the CSV, check assumptions, run the test, and write the APA sentence from the output. From SPSS Output to APA Results Annotated output for the five most common analyses, with the reportable cells highlighted, the usual misreading named, and the APA sentence to write. One Study, Start to Finish One 2×2 study taken through question, design, power, cleaning, assumptions, ANOVA, effect sizes and the finished write-up. One Question, an ANOVA and a Regression The group project many intermediate courses set: three conditions analyzed as an ANOVA, then as a multiple regression with control variables, and the two results reconciled. Reading a Causal-Inference Paper Journal-club preparation: seven questions for judging an instrumental-variables, regression-discontinuity or difference-in-differences design, applied to an invented study.

Which one do you need?

If you do not yet know which analysis you need, start with Choosing Statistics. If you know the test but your file is a mess, start with Clean Your Survey Data. If you have output on screen and a blank Results section, go straight to From SPSS Output to APA. To see all of it once, in order, on one dataset, read One Study, Start to Finish and follow along. If your assignment asks for two analyses of the same question, read One Question, an ANOVA and a Regression. The seventh guide is different: Reading a Causal-Inference Paper is for when you have to judge someone else’s study rather than run your own.

Looking for something shorter? The Statistics Toolbox holds the calculators, printable cheat sheets and reference tables, and the course itself covers every concept these guides use, one interactive lesson at a time.
