1 Establishing Causality
Which of the following is a guideline for establishing causality?
• Look for cases where correlation does not exist between the variables.
The experiment performed should be controlled and randomized.
• Do not consider other possible causes.
• Check if the effect is absent when the response variable is present.
RATIONALE
Finding an association inside an experimental design controls for many other outside
influences and helps to ensure that an explanatory variable always precedes the
response. This helps to support, with strong confidence, that the association is causal.
2 Best-Fit Line and Regression Line
A basketball player recorded the number of baskets he could make depending on how
far away he stood from the basketball net. The distance from the net (in feet) is plotted
against the number of baskets made as shown below.
Using the best-fit line, approximately how many baskets can the player make if he is
standing ten feet from the net?
