Unit 7: Statistical Investigation


This unit addresses the following four components of a statistical investigation: posing the question, collecting the data, analyzing the data, and interpreting the results.  In particular, many lessons address data analysis in graphical and numerical formats.  Graphical representations of data covered include dot plots, histograms, and box plots.  Statistics covered include the following measures of center: mode, median, and mean, along with the following measures of spread: range, interquartile range, and mean absolute deviation.  Emphasis is placed on conceptual understanding of these techniques.  Students will conduct a statistical investigation at the end of the unit.
