561. A doctor studies the relative effectiveness of two drugs of dengue fever. His research would be classified as

Correct Answer: Correct answer is: (C) Experimental Research.

Exam Relevance: GRE, MCAT, Research Methods Exams

Difficulty: Moderate

Concept notes: Experimental research involves manipulating one variable to determine if changes in one variable cause changes in another variable. In this case, the doctor is studying the effectiveness of two drugs, which involves manipulating the type of drug given to patients and observing the outcomes.

Common Mistakes: Students may confuse experimental research with observational studies, where no intervention is made and only natural occurrences are observed.

Explanations: The doctor's study involves manipulating the type of drug given to patients to observe the effects on dengue fever. This manipulation and observation of outcomes align with the definition of experimental research. The study is not merely descriptive, a case study, or ethnographic, as it involves controlled intervention and measurement of outcomes.

Option Analysis:

Option A: Descriptive Survey does not involve manipulation of variables; it merely describes characteristics of a population.
Option B: Case Study focuses on a single individual or a small group in great detail, without manipulating variables.
Option C: Experimental Research involves manipulating one variable to determine its effect on another variable, which fits the scenario described.
Option D: Ethnography involves studying cultures and social behaviors without manipulating variables.

Difficulty: Easy

Concept notes: The introduction section of a research paper sets the stage for the entire study by providing context, scope, and significance. It also clearly states the purpose of the research.

Common Mistakes: Students often confuse the introduction with the review of related literature, which focuses on summarizing existing research rather than setting the context and purpose of the study.

Explanations: The introduction establishes the scope, context, and significance of the research and states the purpose of the study. This aligns with the description provided in the question, making the introduction the correct answer.

Option Analysis:

Option A: Correct. The introduction sets the context, scope, and significance of the research and states the purpose of the study.
Option B: Incorrect. The review of related literature focuses on summarizing existing research and does not establish the context or purpose of the study.
Option C: Incorrect. The methodology section describes the methods and procedures used in the research, not the context or purpose.
Option D: Incorrect. The results and recommendations section presents the findings and conclusions of the study, not the context or purpose.

563. Which of the following is true about the use of deception in research?

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

Exam Relevance: APA Ethics Exam, IRB Training, Research Methods Exams

Difficulty: Moderate

Concept notes: Deception in research involves misleading participants about the true nature of the study. Ethical guidelines require that any deception must be justified by the study's benefits and that participants should be debriefed afterward.

Common Mistakes: Students may mistakenly believe that deception can be used freely in research without any ethical considerations.

Explanations: Deception in research is a sensitive ethical issue. If deception is used, participants must be debriefed to explain the true nature of the study and any potential impacts. Additionally, the use of deception must be justified by the study's benefits, ensuring that the potential knowledge gained outweighs the ethical concerns.

Option Analysis:

Option A: This is incorrect because deception cannot be used anytime without ethical justification and debriefing.
Option B: This is correct because participants may need to be debriefed if deception is used in the study.
Option C: This is correct because the use of deception must be justified by the study's benefits.
Option D: This is correct because both B and C are true statements about the use of deception in research.

Explanations: A scientific theory is a comprehensive explanation of a set of related phenomena, supported by a large body of evidence. It is not just a guess or a simple fact, but a coherent framework that integrates many interconnected facts and observations. Therefore, when large groups of interconnected facts are considered together in a consistent manner, we get a scientific theory.

Option Analysis:

Option A: A combined result is not a comprehensive explanation but rather a summary or outcome of multiple facts.
Option B: A confirmed fact is a single piece of evidence, not a comprehensive explanation of interconnected facts.
Option C: A scientific theory is a well-substantiated explanation that integrates a large number of interconnected facts.

Explanations: Articles published in magazines, journals, and encyclopedias are generally more credible because they undergo rigorous review processes. These sources are often written by experts in the field and are fact-checked to ensure accuracy. In contrast, anonymous comments on social media, personal blogs, and even Wikipedia articles can be less reliable due to the lack of formal review and potential for bias or misinformation.
