Description: In linguistic research, data are often analysed with mixed-effects models. This is because the the data entail repeated measurements: the same participant responds to several items in one or more conditions. Similarly, a given item may be seen by more than one participant. If the data of a study are analysed with a mixed-model, power analyses for that study must be conducted with the same mixed-effects model. Unlike for the t-test, power for a mixed-effects model cannot be computed. It can only be estimated with simulations. In this second workshop, we will learn to simulate data for a continuous dependent variable using linear mixed-effects model. This will allow us to estimate power as well as the sample size(s) needed to achieve a certain power.
