Fitting Models Is like Tetris - Crash Course Statistics

The video introduces general linear models (GLMs) like regression, ANOVA, and ANCOVA, using a Tetris analogy to explain their application in statistical analysis. It reviews ANOVA and regression, highlighting their similarities and the flexibility of ANCOVA. An example involving anesthesia dosage demonstrates ANCOVA's ability to combine categorical and continuous variables. The video discusses using covariates to reduce error and improve model inference. It introduces repeated measures ANOVA for analyzing data with repeated measurements. The conclusion emphasizes the versatility of these models in various applications.

What is the significance of the p-value in the context of the examples provided?

How can ANCOVA models be used to make stronger inferences in research?

What are the potential pitfalls of adding too many covariates in a model?

Discuss the importance of allowing each individual to have their own baseline in repeated measures ANOVA.
