In which of the following ways are correlational designs similar to quasi-experimental designs?
A)They both use nonrandom samples.
B)They both suffer from possible threats to internal validity.
C)They both use random assignment.
D)They both use small numbers of participants.

Both correlational and quasi-experimental designs can suffer from possible threats to internal validity. In correlational designs, there may be confounding variables that affect the relationship between the two measured variables, while in quasi-experimental designs, there may be alternative explanations for the observed differences between groups, which may not be due to the independent variable being studied. However, correlational designs do not involve random assignment, while quasi-experimental designs do. Additionally, sample sizes can vary in both types of designs, so D is not an accurate statement. A is not accurate either, as random sampling can still be used in quasi-experimental designs.
