b. Caitlin is a little concerned that the effect of relationship quality will be weak, and she wants to be sure to detect it. What can she do to make sure her math problem’s dependent variable is a sensitive measure of problem solving? c. What can she do to make sure her math problem’s dependent variable is a construct valid measure of problem solving? d. What else can Caitlin do to make sure she has the best study possible to detect this difficult-to-find effect? (What design should she use and why? How many participants could she use and why? What details of the experimental situation should she be thinking about and why?)
Answer:
Given that:
b) Caitlin is a little concerned that the effect of relationship quality will be weak, and she wants to be sure to detect it. What can she do to make sure her math problem’s dependent variable is a sensitive measure of problem solving?
She should be able to select a math problem that is from the category of word problem as they help probe the problem solving capacity of an individual.
c) What can she do to make sure her math problem’s dependent variable is a construct valid measure of problem solving?
By evaluating it across three measure, the creative ability, the ability to structure the problem provided in an efficient manner, and the skill set used to solve the problem.
d) What else can Caitlin do to make sure she has the best study possible to detect this difficult-to-find effect?
she should implement the experimental study design with two groups: one group with negative impact and the other with positive impact to measure the differences in problem solving, if any.
