# PSYC311 Quantitative Methods

Design and analysis of psychological experiments.

In this paper, students learn how to analyse research data using the general linear model. This model is the basis for most commonly used statistical techniques in psychological research, including analysis of variance (ANOVA), correlation and regression. Students will gain a conceptual understanding of what the model is, how it is used to analyse data and what it teaches us about how research studies should be designed in the first place.
