High School Statistics Foundations
High School Statistics Foundations gives grades 9-12 students a complete, non-AP statistics foundation: categorical and quantitative data, collecting data soundly, probability, random variables, and relationships between variables. Students finish with a full statistical research project, from question to presented findings — preparation for AP Statistics, research, or data science.

Course journey
Follow the ideas as they grow
9 units, in the order they build on each other. Each unit's question is the thing it exists to answer.
Statistical Thinking
What precise vocabulary and notation distinguish a population from a sample, and a parameter from a statistic?
Categorical Data
How do you formally describe and compare entire distributions of a categorical variable, not just one percentage at a time?
One-Variable Quantitative Data
What does it take to fully and formally describe a quantitative distribution's shape, center, and spread?
Comparing Distributions
How do you compare values that come from entirely different distributions?
Collecting Data
What specifically makes an experiment — not just a sample — able to support a claim of causation?
Probability
How do formal set notation and multi-stage reasoning let you solve probability problems too complex for a single rule?
Random Variables
How do you summarize an entire random process with just a few numbers?
Relationships Between Variables
How do you quantify a linear relationship precisely, model it with an equation, and know when to trust that model?
Statistical Research Project
What does it take to design, execute, and honestly report a real statistical research project?
