Course: H.S. Quantitative Reasoning

 

QR.S.5

Read, interpret, and make decisions about data summarized numerically using measures of center and spread, in tables, and in graphical displays (line graphs, bar graphs, scatterplots, and histograms), e.g., explain why the mean may not represent a typical salary; explain the difference between bar graphs and histograms; critique a graphical display by recognizing that the choice of scale can distort information.

Looking Back Looking Ahead

*Organize, graph (e.g., line plots and box plots), and compare univariate data of two or more different data sets using measures of center (mean and median) and spread (range, interquartile range, standard deviation, percentiles, and variance). (MA.AII.DSP.3)
