1535. The experimental study is based on:

Correct Answer: Correct answer is: (D) The manipulation of variables.

Exam Relevance: AP Psychology, GRE Psychology, MCAT

Difficulty: Moderate

Concept notes: Experimental studies involve manipulating one or more variables to observe the effect on another variable.

Common Mistakes: Students may confuse experimental studies with observational studies, which do not involve manipulation of variables.

Explanations: Experimental studies are characterized by the manipulation of variables to establish cause-and-effect relationships. By changing the levels of the independent variable and observing the effect on the dependent variable, researchers can determine if there is a causal relationship between them. This manipulation is a key feature that distinguishes experimental studies from other types of research.

Option Analysis:

Option A: Conceptual parameters are more related to theoretical frameworks and do not involve actual manipulation of variables.
Option B: Replication of research involves repeating a study to verify results, but it does not necessarily involve manipulation of variables.
Option C: Survey of literature involves reviewing existing research but does not involve the manipulation of variables.
Option D: The manipulation of variables is a defining characteristic of experimental studies.

1536. A research problem is visible only when

Exam Relevance: PhD Qualifying Exams, Research Methodology Exams, Academic Journals

Difficulty: Moderate

Concept notes: A research problem is considered visible when it meets multiple criteria: it is researchable, adds new knowledge, and has real-world utility and relevance.

Common Mistakes: Students may overlook the importance of real-world utility and relevance, focusing only on the novelty and researchability of the problem.

Explanations: A research problem is visible when it satisfies all the given conditions. It must be researchable, meaning it can be studied and analyzed using scientific methods. It should also add something new to the existing body of knowledge, making it novel and significant. Additionally, the problem must have utility and relevance in the real world, ensuring that the research has practical applications and can contribute to solving real-world issues. Therefore, all the conditions mentioned in the options are necessary for a research problem to be considered visible.

Option Analysis:

Option A: The problem is researchable, which is a necessary condition for visibility.
Option B: The problem is new and adds something new to the existing knowledge, which is another necessary condition.
Option C: The problem has utility and relevance in the real world, which is also a necessary condition.
Option D: All of the above, which correctly encompasses all the necessary conditions for a research problem to be visible.

Mnemonic: RANU - Researchable, Additive, Novel, Utility

1537. Why is it important to change one variable at a time in single case designs?

Correct Answer: Correct answer is: (C) Both A and B are true.

Exam Relevance: Psychology exams, Research Methods exams, Statistics exams

Difficulty: Moderate

Concept notes: In single case designs, changing one variable at a time is crucial for isolating the cause of any observed changes and avoiding confounding variables.

Common Mistakes: Students may overlook the importance of isolating variables and instead focus solely on the practicality of changing multiple variables.

Explanations: Changing one variable at a time in single case designs allows researchers to isolate the cause of the change, ensuring that any observed effects can be attributed to the manipulated variable. If more than one variable is changed simultaneously, it becomes difficult to determine which variable caused the observed effect, leading to confounding. Therefore, both statements A and B are true, making C the correct answer.

Option Analysis:

Option A: This statement is true because changing one variable allows researchers to isolate the cause of the change.
Option B: This statement is also true because changing more than one variable at a time can confound the independent variables, making it difficult to determine the cause of the observed effect.
Option C: This option correctly identifies that both A and B are true.
Option D: This option is incorrect because both A and B are true.

1538. Which is not a characteristic of Science?

Correct Answer: Correct answer is: (D) Science is not free from emotional bias.

Concept notes: Science is characterized by its reliance on quantitative methods, facts, and hypotheses. However, scientists are human and can be influenced by emotional biases, which can affect their research and conclusions.

Common Mistakes: Students may mistakenly believe that science is entirely objective and free from any form of bias.

Explanations: Science is a human endeavor, and scientists can be influenced by their personal beliefs, societal pressures, and other emotional factors. This means that while science aims to be objective, it is not entirely free from emotional bias.

Option Analysis:

Option A: Science does use quantitative methods, which is a characteristic of science.
Option B: Science is based on facts, which is a characteristic of science.
Option C: Science employs hypotheses, which is a characteristic of science.
Option D: Science is not free from emotional bias, which is not a characteristic of science.
