Probability, Data and Statistical Reasoning

Learners build sample spaces and use the addition and multiplication rules, compute conditional probabilities from two-way tables and test for independence, use normal distributions, the empirical rule and z-scores to estimate proportions and compare values, and distinguish surveys, observational studies and experiments while judging sample estimates with simulation and margins of error.

  • 4 lessons
  • About 130 minutes
  • Probability and statistics check: 11 questions
  • Ways to answer: choose an answer, type a fraction, match pairs, type a number, place on a number line and sort into groups

What learners will discover

  • Describe sample spaces and apply the addition and multiplication rules, including for independent events and draws without replacement.
  • Compute conditional probabilities from two-way tables and decide whether two events are independent.
  • Use normal distributions, the empirical rule and z-scores to estimate proportions and compare values from different distributions.
  • Distinguish surveys, observational studies and experiments, and use simulation and margin of error to judge estimates from samples.
