Option D: Incorrect. The correct answer is clearly inductive reasoning.

10. True or False. In a correlational study, researchers manipulate variables to observe effects.

Correct Answer: Correct answer is: (B) False.

Exam Relevance: AP Psychology, IB Psychology, GRE Psychology

Difficulty: Easy

Concept notes: In a correlational study, researchers do not manipulate variables. Instead, they observe and measure variables to determine if there is a relationship between them.

Common Mistakes: A common misunderstanding is that correlational studies involve manipulation of variables, similar to experimental studies. However, in correlational studies, researchers only observe and measure variables without manipulating them.

Explanations: In a correlational study, researchers do not manipulate variables to observe effects. Instead, they measure variables as they naturally occur to determine if there is a relationship between them. This is in contrast to experimental studies, where researchers manipulate one variable to observe the effect on another variable.

Option Analysis:

Option A: This option is incorrect because in a correlational study, researchers do not manipulate variables.
Option B: This option is correct because in a correlational study, researchers do not manipulate variables; they only observe and measure them.
