Sara sets up an experiment with a control group and a experimental group to study how reading to preschool children may improve their first-grade reading achievement scores. In her study, the independent variable will be
A first-grade reading achievement scores
B reading to children
C being in the experimental group
D having been read to as a preschool.
I belive the correct answer is B

    yes.

    I see little difference between B and D, but D seems to be more precise for this experiment.

  • psychology - ,

    Since the purpose is to "study how reading to preschool children may improve their first-grade reading achievement scores," D would be the independent variable. The first-grade reading scores would be the dependent variable.

    I agree with Ms.Sue.

    I hope this helps a little more. Thanks for asking.
