Kathryn wants to control for intelligence in her study. she has a list of all of the participants for her study and their iq scores. she sorts the list of participants according to their iq scores and then forms groups making sure that the groups are balanced in terms of iq scores. finally, she randomly assigns each group to one of the conditions of her study. She is using matched-group design.
The correlation coefficient r=-0.84 denotes that there is inverse relationship between x and y. It means that as the x values increase the y values decrease whereas as the x values decreases the y-values increases. Also, r=-0.84 denotes the strong relationship between x and y because it is close to 1. So, r=-0.84 denotes that there is strong linear relationship between x and y with smaller x values tending to be associated with larger y values.
