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 circles (making the hole appear larger) than when it was surrounded by larger circles (making the hole appear smaller). What was the independent variable in this experiment? O A. The independent variable in this experiment was the 32 participants. O B. The independent variable in this experiment was the number of successful putts that each participant made. O C. The independent variable in this experiment was the actual size of the golf hole, and its levels were larger or smaller. O D. The independent variable in this experiment was the apparentrsize of the golf hole, and its levels were larger or smaller. SUBMIT 15°C

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 circles (making the hole appear
larger) than when it was surrounded by larger circles (making the hole appear smaller).
What was the independent variable in this experiment?
O A. The independent variable in this experiment was the 32 participants.
O B. The independent variable in this experiment was the number of successful putts that each
participant made.
O C. The independent variable in this experiment was the actual size of the golf hole, and its levels were
larger or smaller.
O D. The independent variable in this experiment was the apparentrsize of the golf hole, and its levels
were larger or smaller.

Follow-up Question
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 circles (making the hole appear
larger) than when it was surrounded by larger circles (making the hole appear smaller).
What was the dependent variable in this experiment?
O A. The dependent variable in this experiment was the 32 participants.
O B. The dependent variable in this experiment was the number of putts each participant made.
O C. The dependent variable in this experiment was the actual size of the gotf hole, and its levels were
larger or smaller.
O D. The dependent variable in this experiment wabthe apparent size of the golf hole, and its levels were
