Students use informal language to describe the shape, center, and variability of a distribution based on a dot plot, histogram, or box plot.

Students recognize that a first step in interpreting data is making sense of the context.

Students make meaningful conjectures to connect data distributions to their contexts and the questions that could be answered by studying the distributions.

Make sense of problems and persevere in solving them.

Reason abstractly and quantitatively.

Model with mathematics.

Use appropriate tools strategically.

Attend to precision.

Look for and make use of structure.

Represent data with plots on the real number line (dot plots, histograms, and box plots).

Use statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets.

Interpret differences in shape, center, and spread in the context of the data sets, accounting for possible effects of extreme data points (outliers).
