Things that I think are important

Chapter 1 Bar graphs, histograms Outliers Mean, median, mode, quartiles of data Variance and standard deviation of data Densities/distributions, skew The Normal distribution and N(0,1) Standardization

Chapter 2 Scatterplots Correlation, covariance* Correlation versus causation Regression: Intuition about what a trendline is Not how to calculate it

Chapter 3 Sample vs. population Statistics vs. parameters Picking a good sample Importance of eliminating bias Importance of randomization Statistical significance Sampling distributions!

Chapter 4

Chapter 5 Probability rules Venn diagrams Conditional probability Definition of independence (p. 299) Bayes’ Rule Binomial setting Binomial distribution Normal approximation of Binomial

Chapter 6 Confidence intervals as a concept Significance testing as a concept Hypotheses P-values Significance level Power as a concept Calculating power for a test Type I and II errors

Chapter 7 Standard error as estimate of standard deviation of sample statistic t-distribution One-sample confidence intervals One-sample t-tests (incl. matched pairs) Two-sample confidence intervals Two-sample t-tests Regular and pooled procedures Ignore Satterwaithe stuff
