Big Ideas: The visual information on dot plots and histograms can help determine the possible number of observations (pieces of data) being displayed. Box plots represent five possible points of data: smallest value, largest value, median, lower quartile, and upper quartile. This lesson asks students to glean information from unlabeled dot plots, histograms, and box plots. Students will recognize that the number of observations (data values) is dependent on the frequency intervals. Students will learn that box plots at the most tell five data points, aside from the minimum and the maximum data values which are always in the data set, the upper quartile, lower quartile and median may not be in the data set. The shape of the data distribution also imparts information such as areas of data concentration. This lesson shows students the importance of interval labeling and is a good lead in to 6.SP.b.5.b Vocabulary: table, mean, median, mode, range, measures of central tendency, dot plot, histogram, box plot, percentile, lower quartile, upper quartile Special Materials: None
