Asking questions and defining problems

Obtaining, evaluating, and communicating information
Recognize a statistical question as one that anticipates variability in the data related to the question and accounts for it in the answers.
Understand that a set of data collected to answer a statistical question has a distribution which can be described by its center, spread, and overall shape.
Display numerical data in plots on a number line, including dot plots, histograms, and box plots.
Informally assess the degree of visual overlap of two numerical data distributions with similar variabilities, measuring the difference between the centers by expressing it as a multiple of a measure of variability.
Integrate quantitative or technical information expressed in words in a text with a version of that information expressed visually (e.g., in a flowchart, diagram, model, graph, or table).
