Option A: Bibliography is a list of all sources used in the research, not just the ones directly cited.
Option B: Citation is the act of referring to another author's work in one's research paper.
Option C: Reference is a general term that can include citation, but citation specifically refers to the act of acknowledging the source within the text.
Option D: None of the above is incorrect as citation is a valid and specific term.

Mnemonic: Cite to Cite: Remember to cite when you use someone else's ideas.

1033. What two questions must be answered in order to select one of the specific mixed method designs provided in the textbook?

Correct Answer: Correct answer is: (D) A and B.

Exam Relevance: Qualitative Research Methods, Quantitative Research Methods, Mixed Methods Research

Difficulty: Moderate

Concept notes: To select a specific mixed method design, two key questions must be addressed: the priority given to qualitative or quantitative paradigms, and the timing of the qualitative and quantitative components.

Common Mistakes: Students may overlook the importance of both the priority and timing aspects, focusing only on one of the two questions.

Explanations: The correct answer is D) A and B. In mixed method designs, it is crucial to determine whether the qualitative or quantitative paradigm will be given priority or if they will be given equal status. Additionally, the sequence of the qualitative and quantitative components must be decided, whether they will be carried out concurrently or sequentially. Both these decisions are essential for selecting an appropriate mixed method design.

Option Analysis:

Option A: This option addresses the priority of the qualitative or quantitative paradigm, which is one of the two necessary questions. However, it does not cover the timing aspect.
Option B: This option addresses the timing of the qualitative and quantitative components, which is the second necessary question. However, it does not cover the priority aspect.
Option C: This option is unrelated to the selection of mixed method designs and does not address the necessary questions.
Option D: This option correctly identifies both necessary questions: the priority of the paradigms and the timing of the components.

1034. When a extraneous variable systematically varies with the independent variable and influences the dependent variable, it is called:

Correct Answer: Correct answer is: (B) A confounding variable.

Exam Relevance: AP Psychology, GRE Psychology, MCAT

Difficulty: Moderate

Concept notes: A confounding variable is an extraneous variable that correlates with both the independent and dependent variables, potentially misleading the results of an experiment.

Common Mistakes: Students may confuse a confounding variable with a moderating variable, which influences the relationship between the independent and dependent variables but does not systematically vary with the independent variable.

Explanations: A confounding variable is an extraneous variable that systematically varies with the independent variable and influences the dependent variable. This systematic variation can lead to misleading conclusions about the relationship between the independent and dependent variables. Therefore, the correct term for such a variable is a confounding variable.

Option Analysis:

Option A: Another dependent variable is incorrect because a dependent variable is the outcome being measured, not an extraneous variable.
Option B: A confounding variable is correct as it describes an extraneous variable that systematically varies with the independent variable and influences the dependent variable.
Option C: A moderating variable is incorrect because it influences the relationship between the independent and dependent variables but does not systematically vary with the independent variable.
Option D: An unreliable variable is incorrect because unreliability refers to the consistency of measurement, not the systematic variation with the independent variable.

1035. When you are writing a biography about someone, the best way to organize the information is:

Correct Answer: Correct answer is: (A) Chronologically.

Exam Relevance: SAT, ACT, AP English Language and Composition

Difficulty: Easy

Concept notes: Organizing a biography chronologically means presenting events in the order they occurred, from the subject's birth to their later life.

Common Mistakes: Students may mistakenly believe that any order is acceptable, but chronological order provides a clear and logical progression of events.

Explanations: Chronological organization is the best way to write a biography because it allows the reader to follow the subject's life in a logical sequence, from early life to later years. This method ensures that the narrative flows naturally and helps the reader understand the context and progression of events.

Option Analysis:

Option A: Correct. Chronological order is the best way to organize a biography.
Option B: Incorrect. Any order would make the biography confusing and difficult to follow.
Option C: Incorrect. Starting with the last events and moving to the beginning would disrupt the logical flow of the subject's life story.
Option D: Incorrect. There is a clear best way to organize a biography, which is chronologically.

Option Analysis:

Option A: This is correct as the passage explicitly states that Sarah and Ruth look alike.
Option B: This is incorrect because the passage states that Sarah is shy and quiet, but Ruth is not shy and loves talking to people.
Option C: This is incorrect because the passage mentions that Sarah's favorite color is pink and Ruth's favorite color is blue, not purple.

Common Mistakes: Students often confuse the independent variable with the dependent variable, which is the outcome measured in response to changes in the independent variable.

Explanations: The independent variable is the factor that the researcher directly manipulates to observe its effect on the dependent variable. In a controlled experiment, the researcher changes the independent variable to determine its impact on the dependent variable.

Option Analysis:

Option A: The dependent variable is the outcome that is measured in response to changes in the independent variable.
Option B: The independent variable is the factor that the researcher manipulates in a controlled experiment.
Option C: A confounding variable is an extraneous variable that can affect the outcome of the experiment and is not controlled for.
Option D: This option is not applicable as the correct answer is provided.
