Topics Included Exploring One-Variable Data Data distributions, measures of center, measures of spread, outliers, boxplots, and histograms. Exploring Two-Variable Data Scatterplots, correlation, linear relationships, regression lines, residual analysis, and association interpretation. Collecting Data Sampling methods, random sampling, surveys, experimental design, observational studies, and sources of bias. Probability Fundamentals Probability concepts, sample space, independent events, conditional probability, probability rules, and Venn diagrams. Random Variables Discrete variables, continuous variables, expected value, variance, and standard deviation. Probability Distributions Binomial distribution, geometric distribution, normal distribution, standard normal curve, z-scores, and applications. Sampling Distributions Sampling distributions, sample means, central limit theorem, standard error, sample proportions, and interpretation. Confidence Intervals Confidence levels, margin of error, estimating means, estimating proportions, critical values, and interpretation. Hypothesis Testing Null hypothesis, alternative hypothesis, test statistics, p-values, significance levels, and decision making. Inference for Means One-sample means, two-sample means, paired data, t-distributions, confidence procedures, and interpretation. Inference for Proportions Population proportions, one-proportion tests, two-proportion tests, confidence intervals, and sampling conditions. Chi-Square Procedures Goodness-of-fit tests, homogeneity tests, independence tests, contingency tables, expected counts, and chi-square statistics. Linear Regression Least squares regression, regression equations, slope interpretation, residuals, coefficient of determination, and model evaluation.
