Question 7 i need to do some research, but i’m not sure whether to use a correlational study or an experiment. i decide to do a laboratory experiment because i a) want something that is very hard to replicate so no one can steal my findings. b) am looking for a relationship between two variables. c) want to determine cause and effect. d) know that psychology can only be studied through experiments, not studies. * only answer if you are 99% sure, .*

The correct answer is option (c) want to determine cause and effect.

The correlation is the  study of two variables with respect to one another. these studies are done, when the scientist want to find the relation between two or more variables.

The experiment is done when the person doing research want to monitor the effect of the change in a particular variable. Hence, one can do experimental study to determine the cause of any phenomena and its effect.
