Linear mixed models

Description

There are two parts of assignment, part 1 is 1000 words, and part 2 is 2000 words. Read the assignment brief and you will know exactly what to do. I am, sending the data file and then putting this data in SPSS software, finding means group sizes and S.D etc. Finding following: 1. Two repeated-measures Analysis of Variance, one over raters (F1) and one over rated individuals (F2) with rating condition and attractiveness as discrete predictors. 2. A standard multiple regression model with rating condition as a discrete predictor and attractiveness as a continuous predictor (ignoring the random effects of rater and rated individual). 3. A linear mixed model with rating condition as a discrete predictor and attractiveness as a continuous predictor and random intercepts for both participant and rated person (as we want to be able to generalise the results beyond the 40 raters and the 20 rated individuals).
