High School Statistics and Probability - how it flows

A draft of the learning progression for HS Statistics and Probability has been released. 

Curious about how to cluster and sequence student learning for this Conceptual Category? Check out how the progression guides us to help students rise to the Stats and Prob bar.

In high school, students build on knowledge and experience described in the 6-8 Statistics and Probability Progression. They develop a more formal and precise understanding of statistical inference, which requires a deeper understanding of probability. Students learn that formal inference procedures are designed for studies in which the sampling or assignment of treatments was random, and these procedures may not be informative when analyzing non-randomized studies, often called observational studies. For example,
a random selection of 100 students from your school will allow you to draw some conclusion about all the students in the school, whereas taking your class as a sample will not allow that generalization.

Probability is still viewed as long-run relative frequency but the emphasis now shifts to conditional probability and independence, and basic rules for calculating probabilities of compound events.
