In module 6, students begin to think and reason statistically. They identify statistical questions and represent data distributions by using dot plots, histograms, relative frequency histograms, and box plots. Students describe the center, spread, and shape of a data distribution. They calculate and interpret measures of center and spread including mean, mean absolute deviation, median, and interquartile range, and they use these measures to describe the typical value and variability of a data distribution. At the end of the module, students complete a project where they develop a statistical question, implement a plan to collect data, analyze and interpret the data they collect, and present their findings to their peers. 

In topic A, students begin to think and reason statistically. They recognize a statistical question as one that can be answered by collecting data values that can vary. They also learn that they can describe a data distribution by describing the center, spread, and shape. In this topic and throughout the module, students visualize and represent data distributions by using dot plots, histograms, and relative frequency histograms.
