Each student should respond with an initial post and at least 1 reply post a peer’s post.  Read the below graph and answer the questions in your initial post.

The data points display the change (either decrease or increase) in running time after switching to a new shoe.

  1. When studying the relationship between two variables, we are looking for an association between them. An explanatory variable is the “input” variable and the response variable is the “output” variable. What is the explanatory variable for this study? What is the response variable?
  2. What is a possible conclusion based on the graph?
  3. A lurking variable is a variable that is not included in a statistical analysis, but may affect the relationship between the explanatory and response variables. It can falsely identify a strong relationship between variables or hide the true relationship. What are possible lurking variables for this study?
