In this lesson students compare NFL QB rating of quarterbacks with and without facial hair.  This task can be used to explore a number of math ideas such as sampling, causation versus correlation, misleading data, measures of central tendency, variability and data visualization.  Questions to consider:

  • Is this enough data to definitively say that facial hair improves quarterback performance?
  • How might we collect a stronger set of data?
  • Does facial hair cause improved quarterback performance or is it a correlation?
  • How can we collect data to show that facial hair reduces quarterback performance?
  • Which measure of central tendency best represents the data?
  • What type of graph or plot can be used to display the data?
