    Answer:

    The correct answer would be – dependent independent variable experiment.

    Explanation:

    Dr. Stein hypothesized that excess sugar causes hyperactivity, so sugar treatment /no sugar treatment would be independent variable. By giving some children sugar and others a sugar cookies he can manipulate the independent variable.

    Similarly , the dependent variable is the result or outcome of independent variable, or what Dr. Stein hypothesize to be the result of excess sugar . In this sugar experiment, then, the dependent variable is the children’s hyper activity level.

    Thus, the correct answer would be – dependent independent variable experiment.
