6.DS.A: Extend understanding of statistical variability.

Extend understanding of statistical variability.

6.DS.A.1Recognize a statistical question as one that anticipates variability in the data related to the question and accounts for it in the answers (e.g., "How old am I?" is not a statistical question, but "How old are the students in my school?" is a statistical question because one anticipates variability in students' ages).6.DS.A.2Use the language of probability (e.g., likely, unlikely, certain, impossible) to describe the likelihood of possible outcomes and to anticipate variability in data collected from statistical questions. Explain how the likelihood of outcomes helps predict which responses may be more or less common in the data and justify predictions using probability terms.6.DS.A.3Explain how a set of data collected to answer a statistical question has a distribution which can be described by its center, spread, and overall shape.6.DS.A.4Recognize that a measure of center (median and/or mean) for a numerical data set summarizes all the values with a single number, while a measure of variation describes how its values vary with a single number.
