## Syllabus

This course aims to familiarize students with executing a variety of statistical tests: t-tests, ANOVA and its different variations, multiple linear regression and more. The principle aim of the course is to enable students to understand which analysis is applicable for each type of data, and execute the proper analyses using R. The main focus will be on usability and application of statistical knowledge in answering research questions, and less on the mathematical background of the statistical methods. No background in programming is needed.

Topics by week:
1. Introduction to R
2. Descriptive statistics
3. Comparing two populations: t-test.
4. Comparing two populations - non-parametric tests
5. One-way ANOVA
6. Multiple comparisons and contrasts
7. Two-way ANOVA
8. Experimental design - randomized block, nested, split-plot
9. Experimental design - repeated measures
10. Data transformation, power calculations
11. Linear regression
12. Correlation + selected topics

## Learning Outcomes

Upon successful completion of this course students should be able to:

1. Determine the appropriate statistical analysis for a given experimental setting.
2. Plan experiments while considering statistical power, sufficient sample size, and avoiding potential statistical "pitfalls".
3. Execute a variety of common statistical tests (e.g., t-tests, ANOVA and its different variations, multiple linear regression, non-parametric analysis) using R (although the knowledge obtained will be applicable for commercial statistical software as well).
4. Critically review statistical analyses conducted in published papers.
