1. Exploring Data
- Graphical Representations: Histograms, dot plots, box plots, stem-and-leaf plots
- Numerical Measures: Mean, median, standard deviation, quartiles, interquartile range
- Probability: Events, sample spaces, probability distributions, conditional probability
2. Sampling and Inference
- Sampling Methods: Simple random sampling, stratified sampling, cluster sampling
- Sampling Distributions: Central Limit Theorem, t-distribution, chi-square distribution
- Estimating Parameters: Confidence intervals, hypothesis testing, p-values
3. Regression and Correlation
- Linear Regression: Least squares line, correlation coefficient, hypothesis testing
- Multiple Regression: Multiple predictor variables, adjusted R-squared
- Residual Analysis: Assumptions of regression, outliers, influential points
4. Experimental Design and Inference
- Experiments: Types of experiments, randomization, blinding
- Analysis of Variance (ANOVA): One-way ANOVA, two-way ANOVA
- Non-parametric Tests: Chi-square test, Kruskal-Wallis test, Mann-Whitney U test
5. Probability and Distributions
- Discrete Probability Distributions: Binomial distribution, Poisson distribution, geometric distribution
- Continuous Probability Distributions: Normal distribution, t-distribution, chi-square distribution
- Sampling Distributions: Central Limit Theorem, sampling error
6. Advanced Topics
- Chi-Square Tests: Goodness-of-fit tests, independence tests
- Non-parametric Tests: Wilcoxon signed-rank test, Friedman test
- Statistical Modeling: Logistic regression, Poisson regression
Tips and Tricks
1. Master Concepts Instead of Memorizing Formulas: Understand the underlying principles to apply formulas correctly.
