List of Biostatistics Topics

Biostatistics is the study of statistical methods applied to biological data and experiments. Biostatisticians analyze data, quantify uncertainty, and test hypotheses using probability and statistical models. Questions ask students to calculate means, standard deviations, and p-values, interpret hypothesis tests and confidence intervals, and apply regression and correlation to biological datasets.

Topics

1. Descriptive Statistics 3 question sets

   • Students summarize data using frequency tables and proportions, calculate mean, median, variance, and standard deviation, and determine percentile ranks from sorted data.

2. Graph Interpretation 4 question sets

   • Students read, interpret, and compare graphical data displays including box plots, histograms, scatterplots, bar charts, ROC curves, and Kaplan-Meier survival plots.

3. Grouping with Z-Scores 2 question sets

   • Students convert raw scores to z-scores, use z-score thresholds to classify observations into groups, and identify statistical outliers using standard deviation cutoffs.

4. Hypothesis Testing Concepts 7 question sets

   • Students formulate and critique null and alternative hypotheses, choose appropriate statistical tests, and interpret p-values, significance levels, and test decisions.

5. Z-Tests, T-Tests, F-Tests, and ANOVA 7 question sets

   • Students analyze biological datasets using one-sample z-tests and t-tests, two-sample t-tests, F-tests for comparing variances, and ANOVA for comparing group means.

6. Chi-Square Tests 3 question sets

   • Students formulate hypotheses, calculate expected counts and chi-square statistics, interpret goodness-of-fit tests for genetic ratios, and identify errors in test procedures.
