## Fall 2014: HS 550

#### Midterm Guide

Please review the following topics, go over the theory and practice for each topic and try to do some problems. The Midterm Exam will be on Monday, Nov 10, 2014, 1:00-2:30PM.

1. Compute 5-number summaries and measures of centrality and variability using data. Example 1. Example 2.
2. Plot data using scatter plot, line plot, dot plot, boxplot, histogram plot, pie chart, etc. Examples.
3. Odds ratio (OR): Estimate of the OR and compute the confidence interval (CI) of the OR. Interpret results. Example.
4. Probability (events, unions, intersections). Example 1. Example 2.
5. Counting (simple permutation and combination examples). Example 1. Example 2.
6. Contingency tables and probabilities of composite events (intersections, unions, conditional probability), e.g., P(Disease | positive Test). Example 1. Example 2.
7. Probability distributions (Normal and Binomial), means, variances, probabilities, critical values. Example 1. Other Examples.
8. Normal Distribution – drawing the area of interest, computing critical and probability values using tables and applet calculators. Examples batch 1. Examples batch 2.
9. Central Limit Theorem (CLT), expectation and standard error of the mean. Examples batch 1. Examples batch 2.
10. Design of Experiments (e.g., comparison,  randomization, replication,  blocking,  orthogonality, placebo). Important DOE characteristics.
The materials in the SMHS EBook, problems we discussed in lecture, labs and forums, and homework problems should be sufficient to prepare for the exam. If you need additional problems, solutions, examples, supplementary materials for these topics, the following resources may be useful:
