Summarize numerical data sets in relation to their context.

Report the number of observations.

Describe the nature of the attribute under investigation, including how it was measured and its units of measurement.

Find the quantitative measures of center (median and/or mean) for a numerical data set and recognize that this value summarizes the data set with a single number. Interpret mean as an equal or fair share. Find measures of variability (range and interquartile range) as well as informally describe the shape and the presence of clusters, gaps, peaks, and outliers in a distribution.
