02 - Plotting relationships (Sept. 14-20)

Relationships between Two Variables

Learning Objectives

  • Display the relationship between two variables by drawing a scatter plot. Be sure to label the axes and include units. 
  • Explain the difference between a response and explanatory variable and label them on the scatterplot.
  • Interpret the plot in terms of direction (positive or negative) and strength of association (how much do the points vary around the average pattern?). 
  • Is a linear relationship reasonable from the scatterplot? If so, explain how to find a model or equation of a line to summarize the relationship. 
  • Be able to measure the strength and direction of a linear relationship with correlation.
