### Learning outcomes

On successful completion of the course students will be able to:

1. Use properties of the probability distribution function to calculate Normal probabilities and Z-scores.

2. Apply exploratory data analysis methods to describe/summarise a distribution and assess whether data are normally distributed.

3. Calculate and interpret Confidence Intervals for means and proportions and state the assumptions on which they are based.

4. Conduct hypothesis tests relating to means and proportions and explain the role of the test statistic, p-value, and significance/Type I error rate.

5. Discuss the difference between statistical significance and clinical significance.

6. Describe the importance of considering power and the Type II error rate during study design.

7. Perform sample size calculations relating to means and proportions for common study designs.

8. Interpret results of commonly used statistical methods as they are presented in published literature.
