7.SP.C.6 Grade 7 · Statistics and ProbabilityApproximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability.Common Core State Standards for Mathematics, as adopted in the Massachusetts Curriculum Framework for Mathematics (2017), Grade 7.
Play the game: Chancefree, no sign-up →Data is counted as dots on a line plot before any average is named, so the shape of the data is seen first.
