bold marks the topics that you better know or I will personally be offended.

• *Measures of location (mean, median, mode, geometric mean)
• *Skewness
• *Variance and Standard Deviation
• Coefficient of Variation (CV)
• Frequency Distribution
• Bar Graphs
• *Histograms
• Stem-and-leaf plots
• *Box plots
• *Probability
  • Independence vs. Dependence
  • Multiplication Law
  • Addition Law
  • Conditional Probability
  • Relative Risk
  • Bayes' Rule (formula in terms of sensitivity, pv+ and so on will be provided)
• PV+, PV-, sensitivity, specificity
• *false-negative, false-positive
• (no ROC curves on the exam)
• *prevalence, incidence
• *Expected Value & Variance of Discrete Random Variables
• *Permutations
• *Combinations
• *Binomial Distribution + its Normal Approx
