Every module we teach, and exactly what is in it
Research statistics taught the way they are actually used — the assumption that chooses the test, the SPSS path in full, and the sentence that reports it.

The SPSS workspace
SPSS looks like one program. It is really four windows that pass work to each other, and each one saves a different kind of file.
Codebook and data entry
The order is the content of this module. Every step is cheap while the ones after it have not happened yet, and expensive once they have.
Getting data in: Excel, Forms, Kobo, REDCap
Every import produces a working file, not a finished one. Keeping them separate is what lets you answer “where did this number come from?” a year later.
Cleaning data you did not collect
Duplicates come first because a duplicated case multiplies every other problem it carries. Outliers come last because you cannot judge an extreme value until the impossible ones are gone.
Missing data
You cannot choose a method before you have a view about the mechanism. Almost every bad decision about missing data is question 3 answered without question 2.
Transform: recode, compute, score
Every transformation in SPSS is one of these four, and every one of them writes to a new variable and leaves the original alone.
Restructure: select, split, merge, long/wide
Every operation in this module answers one of those two questions. The first three are reversible and persistent; the last three change the file itself.
Syntax, and why you should never click twice
This is the whole of Track B, in the order the modules taught it, as five sections of one text file you can re-run from nothing.
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.
