Question

One reason for using random assignment is: (A) to make sure that participants follow the rules of the study(B) to help ensure that participant characteristics don't become confounding variables(C) to give the experimenter control so that he/she can find significant results(D) it is a required component of all psychology studies

Answer 1

(B) to help ensure that participant characteristics don't become confounding variables.

Step-by-step explanation:

This is one of the reasons why we might want to use random assignment when conducting research. Random assignment helps us ensure that participant's characteristics do not become confounding variables. A confounding variable is a variable that affects both the dependent and the independent variable. This could potentially give rise to a spurious association.
