### 02. Video Tutorials (1)

Create dummy variables from an existing categorical variable in SPSS
This video explains how to use SPSS to dummy code categorical variables. Often, this is required if you want to use the variable in regression, but it has more than 2 categories. This resource is contributed to the statstutor Community project by Christine Pereira, Brunel University and reviewed by Vikki O'Neill, Queen's University Belfast.

### 04. Tests and Quizzes (1)

Linear Regression - Numbas
2 questions. Both simple regression. First with 8 data points, second with 10. Find $a$ and $b$ such that $Y=a+bX$. Then find the residual value for one of the data points. Numbas resources have been made available under a Creative Commons licence by Bill Foster and Christain Perfect, School of Mathematics & Statistics at Newcastle University.
