Are 13-year-old boys taller than 13-year-old girls? Display the data in a back-to-back stem-and-leaf graph to investigate the truth of this conjecture. Identify the median for girls and boys and use the two means to help draw a conclusion about this question. Use the tutorial to show the features and uses of stem-and-leaf graphs. This learning object is one in a series of five learning objects.
Objective
1. Students interpret and explore two sets of data represented in back-to-back stem-and-leaf graphs.
2. Students use data and data handling processes to assist in identifying the truth behind a theory.
3. Students compare information derived from two data sets.
