Which of the following conditions are true about a research project in a well-controlled laboratory environment?

Question

A.
High external validity and low internal validity.

B.
High internal validity and low external validity.

C.
Low external validity and low internal validity.

D.
High external validity and high internal validity.

Answer 1

In a well-controlled laboratory environment, the typical outcomes regarding internal and external validity are as follows:

• High internal validity: This means that the study can effectively demonstrate a cause-and-effect relationship due to the control of confounding variables.
• Low external validity: This indicates that the findings of the study may not generalize well to real-world situations, as laboratory settings can differ significantly from real-world conditions.

Based on this reasoning, the correct answer is:

B. High internal validity and low external validity.
