Use a line plot to explore distribution and variation of football players’ heights in this interactive from MPT. In the accompanying classroom activity, students use the interactive and then gather numeric data from classmates on topics such as height and number of pets. Each pair uses one of these data sets to create and analyze a line plot. Students conclude by considering ways that line plots facilitate summarizing and analyzing data sets. To get the most from the lesson, students should be comfortable adding and subtracting fractions with unlike denominators. For a longer self-paced student tutorial using this media, see "Displaying Data With Line Plots" on Thinkport from Maryland Public Television.
