Question

An experimenter is interested in hyperactivity and diet. She believes that the greater the amounts of certain food dyes that are consumed, the more hyperactive a child will be. She looks at children considered hyperactive, and children not considered hyperactive, and then measures the amount of these food dyes that each child consumes in an average month. The amounts vary from 0 to 500 mg. What statistic would enable her to determine if there is a relationship between hyperactivity and consumption of these food dyes

Answer 1

r-squared or r

Explanation:

The statistic that would enable the experimenter determine if there is a relationship between hyperactivity and the consumption of these food dyes is "r-squared or r"

r-squared is a statistical measure used to represent the proportion of the variance for a dependent variable when compared or explained by an independent variable. the variables in this experiment are the food dyes and hyperactivity and to measure the proportion of variance of the dependent variable when explained by an independent variable, r-squared or r is used .
