Topic List – AP Statistics Relative Frequency Two-way tables Marginal Distributions Conditional Distributions Side-by-side Graphs v. Segmented Bar Graph Association Dotplot Stemplot Histogram SOCS Symmetric/Skew/Modes Variability Mean/Median IQR, Q1, Q3, Outlier Five-number summary Variance/Standard Deviation What’s resistant? Ch. 2 Z-scores Percentiles Cumulative Relative Frequency Graph Data Transformations Density Curves Normal Distributions Normal Probability Plot (we didn’t cover but if you understand it means you understand normality) Chapter Three Scatterplots Explanatory/Response Variable Direction/Form/Strength/Outliers Direction: Positive Association/Negative Association Form: Linear? Strength: r? Correlation, r Causation? Regression Line Meaning of y-int of regression line Slope meaning of regression line Extrapolation – good thing? LSRL Residuals and the residual plot Standard deviation of residuals – what does it measure? r-squared – what is it explaining. Use the exact words!! Outliers influential? Chapter Four Census Population Sample Sample Survey – all the types and all the problems How about bias and variability? Experiment or Observational studies What can we infer from both What do you need in an experiment? Comparison, Assignment, Control, Replication Randomized Design Placebo and the Placebo effect Double-blind/Single-blind Blocking/Matched pairs Scope of the inference from Observational Study/Experiment Chapter Five Law of Large Numbers Simulation: State/Plan/Do/Conclude Probability of an Event … P(Event) Rules of Probability Mutually Exclusive Events Independent Events Exam Tip p. 313. Don’t leave your responses “naked.” Probability model Complement Two-way table or Venn diagram for Union/Intersection Conditional Probability Tree diagrams in Probability Multiplication Rule Chapter Six Distribution of a Random Variable Expected Value Variance and Std Deviation of a discrete random variable Discrete? Continuous Random Variables Transforming/Combining Random Variables Linear transformation of a random variable Variance of two independent random variables Sum or difference of independent Normal random variables Binomial Setting Binomial probability Binomial Random distribution Mean and Standard Deviation of binomial random vaiable X 10% condition … why? Normal Approximation … Large counts condition … why? Geometric setting Geometric probability
