Overview
A statistics guide covering center, spread, normal-model thinking, and probability rules that students search before quizzes and finals.

Key topics
•mean median and variability
•z scores and normal curves
•basic probability rules
•independence and conditional probability

Suggested study tasks
•summarize one dataset with the right measures
•interpret a z score in context
•set up one conditional probability question

Common pitfalls
•using the mean for heavily skewed data
•adding probabilities that are not mutually exclusive
•mixing independence with disjoint events
