• Use frequency distributions and cross-tabulations to organize, summarize, and present data insights effectively.
• Create and interpret visual representations of descriptive statistics (e.g., pie charts, line graphs) to communicate statistical findings clearly.
• Apply basic probability concepts and rules to calculate probabilities and understand the likelihood of events.
• Differentiate between probability distributions (normal and binomial), and explain the significance of the Central Limit Theorem in the context of sampling distributions.
