Learning goals: Teacher Facing Compare and contrast (orally and in writing) box plots that represent different data sets, including ones with the same median but very different IQRs and vice versa. Determine what information is needed to solve problems about comparing box plots. Ask questions to elicit that information. Interpret a box plot to answer (orally) statistical questions about a data set. Full lesson plan (warm-up, activities, synthesis, cool-down prompt) from 6.8 Data Sets and Distributions, Grade 6.
