Data representation, distributions, and statistical variability using sampling and inference techniques. Integrates probability models, compound events, bivariate patterns, and linear models to guide data-driven decision making.

Data DistributionsAnalyzes the shape, center, and spread of numerical datasets using histograms, box plots, and dot plots. Examines measures of central tendency and variability to interpret data consistency and skewness.
Statistical VariabilityAnalysis of data spread using range, interquartile range, and mean absolute deviation. Examines how individual data points differ from the center and from each other within a distribution.
Probability ModelsStatistical analysis using sample spaces, tree diagrams, and area models to predict outcomes. Calculates probabilities of simple and compound events while comparing theoretical results to experimental data.
Compound Event ProbabilitiesCalculation methods for independent and dependent event outcomes using the multiplication rule. Addresses sample space mapping through tree diagrams and tables to determine multi-stage probabilities.
Statistical SamplingRandom, stratified, and cluster sampling methods for data collection and analysis. Addresses sample size determination, bias reduction, and the principles of making valid inferences about larger populations.
Interpret Categorical and Quantitative DataStatistical analysis techniques for summarizing and visualizing numerical and non-numerical data sets. Emphasizes shape, center, spread, and the impact of outliers on data interpretation through dot plots, histograms, and box plots.
Comparing Two PopulationsHypothesis testing and confidence intervals for means and proportions using independent and paired samples. Addresses effect sizes and significance levels to determine statistical differences between distinct groups.
Independence and Conditional ProbabilityCalculation of event likelihood based on prior conditions and methods for identifying statistical independence. Utilizes the multiplication rule, tree diagrams, and Bayes' Theorem to solve complex probability problems.
Probability-Based Decision MakingExpected value calculations and risk assessment techniques for making informed choices under uncertainty. Equips students with decision trees and Bayesian reasoning to evaluate potential outcomes in real-world scenarios.
Statistical Inference and ConclusionsHypothesis testing, confidence intervals, and p-values used to draw population conclusions. Evaluates statistical significance and error types within experimental and observational data.
