How are correlational studies different from experiments?
A) Causation can be inferred.
B) Causation cannot be inferred.
C) The variable is manipulated by the researcher.
D) They are part of qualitative research.
Show Answer
Correct Answer:
Correct answer is: (B) Causation cannot be inferred.
Exam Relevance:
AP Psychology, GRE Psychology, MCAT
Difficulty:
Moderate
Concept notes:
Correlational studies measure the relationship between variables but do not establish causation. In contrast, experiments manipulate variables to determine causation.
Common Mistakes:
A common misunderstanding is that correlational studies can establish causation, which they cannot.
Explanations:
Correlational studies observe and measure the relationship between two or more variables without manipulating them. This means that while a correlation can indicate a relationship between variables, it does not provide evidence that one variable causes the other. In contrast, experiments involve the manipulation of an independent variable to observe its effect on a dependent variable, allowing for inferences about causation.
Option Analysis:
Option A:
This is incorrect because correlational studies do not allow for the inference of causation.
Option B:
This is correct because correlational studies cannot establish causation.
Option C:
This is incorrect because in correlational studies, variables are not manipulated by the researcher.
Option D:
This is incorrect because correlational studies are part of quantitative research, not qualitative research.
