1. Hazel gave her control and experimental groups an assessment before their exposure to the different treatments. Then, gave them another assessment after the exposure.

Correct Answer: Correct answer is: (B) Pretest-Posttest Only.

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

Difficulty: Moderate

Concept notes: In research design, the Pretest-Posttest Only design involves measuring the dependent variable before and after the treatment in both the control and experimental groups. This design helps to assess the effect of the treatment by comparing the changes in the dependent variable.

Common Mistakes: A common misunderstanding is confusing this design with the Solomon Four Group design, which includes both pretest and posttest conditions but also has additional groups that do not receive the pretest.

Explanations: Hazel's design involves giving both the control and experimental groups an assessment before and after the treatment. This aligns with the Pretest-Posttest Only design, where the pretest and posttest are conducted to measure the effect of the treatment. The pretest helps to establish a baseline, and the posttest measures the changes after the treatment, allowing for a comparison of the groups.

Option Analysis:

Option A: Posttest Only does not include a pretest, which Hazel's design does.
Option B: Pretest-Posttest Only correctly describes Hazel's design, as both groups are assessed before and after the treatment.
Option C: Solomon Four Group design includes additional groups that do not receive the pretest, which is not the case in Hazel's design.
Option D: Factorial design involves multiple independent variables, which is not described in Hazel's design.
Option E: Crossover design involves participants receiving both treatments in a sequential manner, which is not described in Hazel's design.

2. Another factor to consider is how participants were recruited for the study when criticizing the research

Concept notes: A within-subjects design compares the same participants under different conditions or at different times. This design allows researchers to observe changes within the same individuals, reducing variability due to individual differences.

Common Mistakes: A common misunderstanding is confusing within-subjects design with cross-sectional design, which compares different groups of people at one point in time.

Explanations: The within-subjects design is the correct answer because it involves measuring the same participants under different conditions or at different times. This design is particularly useful for observing changes or effects within the same individuals, as it controls for individual differences that could confound the results.

Option Analysis:

Option A: Cross-sectional design compares different groups of people at one point in time, not the same people at different times or conditions.
Option B: Between-subjects design compares different groups of people under different conditions, not the same people.
Option C: Longitudinal design involves repeated observations of the same individuals over a long period, but it does not necessarily compare different conditions.
Option D: Within-subjects design compares the same individuals under different conditions or at different times, which matches the description in the question.

Mnemonic: Within-Subjects: "W" for "Within" and "S" for "Same" participants.

7. Division of the sample into groups so that every individual has an equal chance of being put in the experimental group or the control group.

Correct Answer: Correct answer is: (C) Random assignment.

Exam Relevance: AP Psychology, GRE Psychology, MCAT

Difficulty: Moderate

Concept notes: Random assignment is a method used in research design to ensure that each participant has an equal chance of being assigned to either the experimental group or the control group. This helps to eliminate bias and ensures that the groups are comparable.

Common Mistakes: A common misunderstanding is confusing random assignment with random sampling. Random sampling involves selecting participants from a population, while random assignment involves assigning participants to groups within a study.

Explanations: Random assignment ensures that every individual in the sample has an equal chance of being placed in the experimental group or the control group. This method helps to balance out any potential confounding variables, making the groups comparable and the results more reliable.

Option Analysis:

Option A: Single blind refers to a study design where the participants do not know whether they are in the experimental or control group, but the researchers do. This does not describe the process of assigning participants to groups.
Option B: Double blind refers to a study design where neither the participants nor the researchers know who is in the experimental or control group. This also does not describe the process of assigning participants to groups.
Option C: Random assignment is the correct term for the process of dividing the sample into groups so that every individual has an equal chance of being placed in the experimental or control group.
Option D: Random sampling refers to the method of selecting participants from a population, not the method of assigning them to groups within a study.

Mnemonic: RA = Random Assignment
