How to use the statistical parametric mapping (SPM) Matlab examples to structure your own data and tests. My SPM demo video used a t-test as an example but I've received a number of comments and emails asking about other tests. This video shows how to figure out any of the other statistical parametric mapping tests, using an SPM One Way ANOVA as an example.
