Card 24 / 54: To explore her hypothesis, Sam designed the following experiment. Two groups of participants took the musical ability test. Group "A" came back to the lab every day and practiced memorizing words. Group "B" came back to the lab every day and read the same lists of words, but did not memorize them. Then the two groups took the music ability test again. Sam hypothesized that having to memorize the words would cause people to do better on the music test. In Sam's experiment:
A) Group A is the independent variable; Group B is the dependent variable.
B) Group A is the dependent variable; Group A is the independent variable.
C) Group A is in the experimental condition; Group B is in the control condition.
D) Group A is in the control condition; Group B is in the experimental condition.
