1. Internal validity is concerned with ..... whereas external validity is concerned with .....

Correct Answer: Correct answer is: (B) Causality, generalizability.

Exam Relevance: AP Psychology, GRE Psychology, Research Methods in Psychology

Difficulty: Easy

Concept notes: Internal validity refers to the extent to which a study can establish a cause-and-effect relationship between variables. External validity refers to the extent to which the results of a study can be generalized to other settings, populations, or times.

Common Mistakes: A common misunderstanding is confusing internal validity with external validity. Some may think that internal validity is about generalizability, but it is actually about establishing causality.

Explanations: Internal validity is concerned with causality because it focuses on whether the independent variable truly causes changes in the dependent variable. External validity is concerned with generalizability because it assesses whether the findings can be applied to broader contexts beyond the specific study.

Option Analysis:

Option A: Incorrect because generalizability is associated with external validity, not internal validity.
Option B: Correct because internal validity is concerned with causality, and external validity is concerned with generalizability.
Option C: Incorrect because consistency is not a primary concern of internal validity.
Option D: Incorrect because consistency is not a primary concern of external validity.

2. Does the following experiment use quantitative or qualitative data?"Justice asked all of the teachers what their favorite TV show is."

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

Exam Relevance: AP Psychology, IB Psychology, GRE Psychology

Difficulty: Easy

Concept notes: Qualitative data involves non-numerical information, such as descriptions, opinions, or preferences. Quantitative data involves numerical information that can be measured or counted.

Common Mistakes: A common mistake is to confuse qualitative data with quantitative data. Qualitative data focuses on descriptive information, while quantitative data focuses on numerical information.

Explanations: The experiment involves asking teachers about their favorite TV show, which is a descriptive, non-numerical response. This type of data is qualitative because it captures personal preferences and opinions rather than numerical measurements.

Option Analysis:

Option A: This option is incorrect because the data collected is not numerical or measurable, which are characteristics of quantitative data.
Option B: This option is correct because the data collected is descriptive and non-numerical, which are characteristics of qualitative data.

3. Form of research designed to obtain information on how consumers feel about certain products, services, companies, or ideas. Customers are usually asked to rank "how satisfied" they are with a product.

Concept notes: Attrition refers to the reduction in the number of research participants as some drop out of the study over time.

Common Mistakes: A common misunderstanding is confusing attrition with other research biases or processes, such as confirmation bias or debriefing.

Explanations: Attrition is the term used to describe the loss of participants in a study over time. This can occur due to various reasons such as participants dropping out, moving away, or losing interest. It is a critical issue in longitudinal studies where maintaining a consistent sample size is important for the validity of the results.

Option Analysis:

Option A: Correct. Attrition is the term for the reduction in the number of research participants over time.
Option B: Incorrect. Confirmation bias refers to the tendency to favor information that confirms one's preconceptions or hypotheses.
Option C: Incorrect. Debriefing is the process of informing participants about the nature of the study after their participation.
Option D: Incorrect. This option is not applicable as the correct term is attrition.

Mnemonic: A: Attrition, Always Away

5. Rene grew bacteria from the mouth on special plates in the laboratory. She placed drops of different mouthwashes on bacteria on each plate. What step of the scientific method is this?

Correct Answer: Correct answer is: (C) Experiment.

Exam Relevance: AP Biology, IB Biology, MCAT

Difficulty: Moderate

Concept notes: The scientific method involves several steps: asking a question, forming a hypothesis, conducting an experiment, analyzing data, and drawing conclusions. In this scenario, Rene is conducting an experiment by placing different mouthwashes on bacteria to observe their effects.

Common Mistakes: A common misunderstanding is confusing the experiment with the hypothesis. The hypothesis is a proposed explanation or prediction, while the experiment is the actual process of testing that prediction.

Explanations: Rene is conducting an experiment by placing different mouthwashes on bacteria to observe their effects. This step involves manipulating variables (the different mouthwashes) and observing the outcomes (the growth or inhibition of bacteria). This aligns with the experimental phase of the scientific method.

Option Analysis:

Option A: This is incorrect because the question is about the step Rene is performing, not the initial question she might have asked.
Option B: This is incorrect because forming a hypothesis involves making a prediction, not conducting the actual test.
Option C: This is correct because Rene is actively testing the effects of different mouthwashes on bacteria, which is the experimental phase.
Option D: This is incorrect because drawing conclusions comes after the experiment, not during it.

6. T/F: Scientists use climate models to describe how different variables affect and predict Earth's future climate.

Exam Relevance: GRE, MCAT, AP Psychology, Undergraduate Research Methods

Difficulty: Moderate

Concept notes: The scientific method is a systematic approach to inquiry that aims to reduce human biases by relying on empirical evidence, hypothesis testing, and peer review.

Common Mistakes: A common misunderstanding is that the scientific method is only applicable to natural sciences, but it is a general method that can be applied to any field of inquiry.

Explanations: The scientific method involves formulating hypotheses, designing experiments to test these hypotheses, collecting and analyzing data, and drawing conclusions based on the evidence. This process helps minimize the impact of human biases by ensuring that conclusions are based on objective, empirical evidence rather than subjective opinions or preconceived notions.

Option Analysis:

Option A: Psychology is a field of study that can use the scientific method but is not itself a method for reducing human biases.
Option B: The scientific method is a systematic approach that reduces human biases through empirical evidence and rigorous testing.
Option C: A theory is a well-substantiated explanation but does not inherently reduce human biases; it is a product of the scientific method.
Option D: A hypothesis is a proposed explanation but does not itself reduce human biases; it is a step in the scientific method.
Option E: Research is a broad term that encompasses various methods, including the scientific method, but is not specific to reducing human biases.

10. If I have a coin purse full of unknown coins and I pull out two copper pennies and I assume that all the rest of the coins in the purse are copper pennies I am using ..... reasoning.

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

Exam Relevance: GRE, GMAT, LSAT, Research Methods Exams

Difficulty: Easy

Concept notes: Inductive reasoning involves making generalizations based on specific observations. In this case, observing two copper pennies and assuming all other coins are copper pennies is an example of inductive reasoning.

Common Mistakes: A common misunderstanding is confusing inductive reasoning with deductive reasoning. Deductive reasoning starts with a general statement and reaches a specific conclusion, whereas inductive reasoning starts with specific observations and makes a generalization.

Explanations: The reasoning in the question involves making a generalization (all coins are copper pennies) based on specific observations (two copper pennies). This is a classic example of inductive reasoning, where specific instances are used to infer a broader conclusion.

Option Analysis:

Option A: Abductive reasoning involves forming the best explanation for a set of observations, which does not fit the scenario described.
Option B: Inductive reasoning involves making a generalization based on specific observations, which fits the scenario described.
Option C: Analogical reasoning involves drawing comparisons between two similar situations, which does not fit the scenario described.
Option D: Deductive reasoning involves deriving specific conclusions from general principles, which does not fit the scenario described.

Frequently Asked Questions

What is the primary purpose of research methods?
