Chi-square tests
Chi-square goodness of fit and chi-square test of independence, and which question each answers.
One-sample and independent-samples t-test
What question each t-test answers.
Paired-samples t-test
What makes data paired - before/after, matched pairs, two measures on the same person.
One-way ANOVA and post hoc
Why three t-tests is the wrong answer, with the inflated-error arithmetic on the slide.
Two-way and factorial ANOVA
Main effects and interaction, explained before any output appears.
Repeated measures ANOVA
When measurements are repeated on the same participants and why that demands a different test.
ANCOVA
What a covariate does and what "adjusted means" means.
E · Relationships and prediction
Correlation
What r measures and what it does not.
Simple linear regression
What regression adds that correlation does not - a prediction and a unit.
Multiple linear regression
What "holding the others constant" means and why it is the whole point.
Binary logistic regression
Why a yes/no outcome breaks linear regression.
Ordinal and multinomial logistic regression
When the outcome has three or more categories, and whether their order matters.
Moderation and mediation with PROCESS
The difference between a moderator and a mediator, with a diagram for each and a study where each is the right question.
F · Scales and multivariate
MANOVA
When several dependent variables belong in one analysis, and when they do not.
G · Specialist methods
Survival analysis
Time-to-event data and why it cannot be analysed as a simple outcome.
How it is sold
Take one module, a track, or the whole thing
Every module can be bought on its own if you only need one test. Most people take a programme — a named bundle that covers a whole job of work — and the modules you have already finished carry across if you upgrade later.
