Here is the description of the study again: In the study, 32 participants putted a golf ball to a 5- centimeter golf cup. Each participant attempted a total of 20 putts. The researchers wrote, "A downward-facing projector displayed a ring of 11 small (3.8 centimeters in diameter) or 5 large (28 centimeters) circles around each hole to create an Ebbinghaus illusion." For each illusion, participants "attempted 10 putts from a distance of 3.5 meters, and we recorded how many putts dropped into the hole" (Witt et al., 2012, p. 397). The researchers hypothesized that participants wwould make more putts when the hole was surrounded by smaller circles (making the hole appear larger) than when it was surrounded by larger circles (making the hole appear smaller). What are the 32 participants? O A. They are the population. O B. They are a confounding variable. O C. They are an interval variable. O D. They are the sample.

RESEARCH DESIGN: CAN A VISUALLLUSION IMPROVE SPORTS PERFORMANCE? 6 OF 9
Here is the description of the study again: In the study, 32 participants putted a golf ball to a 5-
centimeter golf cup. Each participant attempted a total of 20 putts. The researchers wrote, "A
downward-facing projector displayed a ring of 11 small (3.8 centimeters in diameter) or 5 large (28
centimeters) circles around each hole to create an Ebbinghaus illusion." For each illusion,
participants "attempted 10 putts from a distance of 3.5 meters, and we recorded how many putts
dropped into the hole" (Witt et al., 2012, p. 397). The researchers hypothesized that participants
would make more putts when the hole was surrounded by smaller čircles (making the hole appear
larger) than when it was surrounded by larger circles (making the hole appear smaller).
What are the 32 participants?
O A. They are the population.
O B. They are a confounding variable.
O C. They are an interval variable.
O D. They are the sample.
