Unit Length and Description:

24 days

In Unit 6, students develop an understanding of statistical variability and apply that understanding as they summarize, describe, and display distributions. In particular, careful attention is given to measures of center and variability.  Students will begin to use dot plots, histograms, and box plots to represent and analyze data distributions for quantitative data and use bar graphs to represent and analyze data distributions.  Students will also examine relationships among multiple representations of the same data set.  Students should examine the relationships among making a graph, computing a mean, and predicting a trend rather than viewing these as independent activities.

Standards:

Enduring Understandings:

·         Data can be collected, organized, sorted, represented, and analyzed in a variety of ways.

·         The results of a statistical investigation can be used to support or refute an argument.

·         A statistical question should anticipate variability or more than one answer.

Essential Questions:

·         What is the best way to summarize data collected from a study?

·         How can understanding and use of measures of central tendency be useful for interpreting and drawing conclusions about data?

·         What does variability mean?

·         What is the difference between measures of center and measures of variation?

·         How do you ask a question to collect statistical data?
