Correct Answer: Correct answer is: (A) Characters, setting.

Exam Relevance: SAT, ACT, AP English Literature

Difficulty: Easy

Concept notes: The exposition is the introductory part of a story where the setting and characters are introduced to the audience.

Common Mistakes: Students may confuse the exposition with other parts of the plot structure, such as the climax or resolution.

Explanations: During the exposition, the author sets the stage for the story by introducing the characters and the setting. This is crucial for establishing the context and background necessary for the plot to unfold.

Option Analysis:

Option A: Correct. The exposition introduces the characters and setting.
Option B: Incorrect. The falling action occurs after the climax, not during the exposition.
Option C: Incorrect. The climax and conflict are typically introduced later in the story, not during the exposition.
Option D: Incorrect. The conflict and resolution are part of the rising action and conclusion, not the exposition.

384. This observation is done when everyone knows they are being observed.

Explanations: Overt observation is characterized by the subjects' awareness of the observation. This transparency can influence the subjects' behavior, as they may alter their actions knowing they are being watched.

Option Analysis:

Option A: Correct. Overt observation is when the subjects are aware they are being observed.
Option B: Incorrect. Covert observation is when the subjects are unaware they are being observed.
Option C: Incorrect. The correct answer is not either of the options but specifically overt observation.
Option D: Incorrect. The correct answer is overt observation, not neither of the options.

Mnemonic: Overt: Openly Visible

385. Which of the following is NOT a general feature that characterizes most qualitative research?

Correct Answer: Correct answer is: (D) Inflexible design.

Exam Relevance: Research Methods, Qualitative Research, Social Science Research

Difficulty: Moderate

Concept notes: Qualitative research typically involves a flexible design that allows for adaptation and exploration during the research process.

Common Mistakes: Students may mistakenly believe that qualitative research requires a rigid and predetermined structure, similar to quantitative research.

Explanations: Qualitative research is characterized by its holistic perspective, naturalistic inquiry, and personal contact and insight. These features allow for a flexible design that can adapt to the context and emerging insights during the research process. Inflexible design is not a characteristic of qualitative research, as it would limit the researcher's ability to explore and understand the phenomenon in depth.

Option Analysis:

Option A: Holistic perspective is a key feature of qualitative research, as it aims to understand the whole context and complexity of the phenomenon being studied.
Option B: Naturalistic inquiry is another core feature, as qualitative research often takes place in natural settings and seeks to understand phenomena in their natural context.
Option C: Personal contact and insight are essential in qualitative research, as they allow researchers to gain deep and nuanced understanding through direct interaction with participants.
Option D: Inflexible design is not a characteristic of qualitative research, as it would hinder the researcher's ability to adapt and explore the research context.

386. A researcher examines a program looking at the effects of mentoring on poor readers' reading achievement. He looks at two different schools. One serves as the control and the other the experimental group. Both schools had reading achievement that was around the 50th percentile. During the time that the mentoring program is in place in the experimental group, a statewide reading initiative is started in randomly selected schools. The experimental, but not the control school is involved in the initiative. At the end of the year, the experimental group does better than the control. From the information presented above, a likely threat to the internal validity of the study is:

Correct Answer: Correct answer is: (B) Selection-history effect.

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

Difficulty: Moderate

Concept notes: The selection-history effect occurs when an external event (history) affects the experimental group differently from the control group, potentially confounding the results.

Common Mistakes: Students may confuse this with other threats to internal validity, such as selection-maturation effect or selection-mortality interaction.

Explanations: The statewide reading initiative, which only affects the experimental group, introduces an external factor that could influence the reading achievement. This external event (history) differentially impacts the experimental and control groups, leading to a potential confounding effect. Therefore, the selection-history effect is a likely threat to the internal validity of the study.

Option Analysis:

Option A: Selection by mortality interaction refers to the interaction between the selection of participants and the loss of participants over time, which is not relevant here.
Option B: Selection-history effect is the correct answer as the statewide reading initiative affects the experimental group but not the control group.
Option C: Mortality refers to the loss of participants over time, which is not mentioned in the scenario.
Option D: Selection-maturation effect refers to the natural development of participants over time, which is not the primary issue in this scenario.

387. What is a focus group?

Correct Answer: Correct answer is: (A) A group of people assembled to participate in a discussion about a product before it is launched.

Exam Relevance: AP Psychology, IB Business Management, Marketing Exams

Difficulty: Easy

Concept notes: A focus group is a qualitative research method used to gather opinions and insights from a targeted group of individuals.

Common Mistakes: Students may confuse a focus group with a survey or an interview, which are different methods of gathering information.

Explanations: A focus group involves a group of people who are brought together to discuss a specific topic, such as a product, under the guidance of a moderator. This method is used to gather detailed feedback and insights that can be used to improve the product or service.

Option Analysis:

Option A: Correct. This accurately describes a focus group.
Option B: Incorrect. This describes a survey or questionnaire, not a focus group.
Option C: Incorrect. This describes an interview, not a focus group.
Option D: Incorrect. This describes observation, not a focus group.

Mnemonic: Focus Group: "F" for "Focus" and "G" for "Group" - "F"ocus on "G"roup discussion.

388. Assuming innocence until proven guilty, a Type I error occurs when an innocent person is found guilty.

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

Exam Relevance: AP Statistics, GRE, MCAT

Difficulty: Easy

Concept notes: A Type I error occurs when a true null hypothesis is incorrectly rejected. In the context of legal proceedings, the null hypothesis is that the defendant is innocent. Therefore, a Type I error would be finding an innocent person guilty.

Common Mistakes: Students may confuse Type I and Type II errors, where a Type II error would be failing to find a guilty person guilty.

Explanations: In legal proceedings, the null hypothesis is that the defendant is innocent. A Type I error occurs when this null hypothesis is incorrectly rejected, meaning an innocent person is found guilty. This aligns with the definition of a Type I error in statistical hypothesis testing.

Option Analysis:

Option A: Correct. A Type I error in legal proceedings means an innocent person is found guilty.
Option B: Incorrect. This would imply that a Type I error does not occur when an innocent person is found guilty, which is false.
Option C: Incorrect. This option suggests the statement is neither true nor false, which is not accurate given the definition of a Type I error.
Option D: Incorrect. This option implies none of the above, which is not correct as Option A is true.

389. If the purpose of research is to discover the relative incidence, distribution and inter-relationship of sociological and psychological variables it is called

Correct Answer: Correct answer is: (B) Survey research.

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

Difficulty: Moderate

Concept notes: Survey research is a method used to collect data from a sample of individuals to understand the distribution, incidence, and inter-relationship of sociological and psychological variables.

Common Mistakes: Students may confuse survey research with experimental research, which involves manipulating variables to establish cause-and-effect relationships.

Explanations: Survey research is the correct answer because it involves collecting data from a sample of individuals to understand the distribution, incidence, and inter-relationship of sociological and psychological variables. This method is particularly useful for descriptive and correlational studies where the goal is to understand patterns and relationships within a population.

Option Analysis:

Option A: Experimental research involves manipulating variables to establish cause-and-effect relationships, which is not the focus of the question.
Option B: Survey research is the correct choice as it aims to discover the relative incidence, distribution, and inter-relationship of sociological and psychological variables.
Option C: Ex post-facto research involves analyzing existing data to identify patterns, but it does not specifically focus on the distribution and inter-relationship of variables as survey research does.
Option D: Field experiments involve manipulating variables in a natural setting, which is not the focus of the question.

390. The Method section of the research plan typically specifies

Correct Answer: Correct answer is: (D) All the above.

Exam Relevance: Psychology exams, Research Methods exams, Social Science exams

Difficulty: Moderate

Concept notes: The Method section of a research plan typically includes detailed descriptions of the research participants, apparatus, instruments, materials, and the planned procedures.

Common Mistakes: Students may overlook the comprehensive nature of the Method section and assume it only covers one or two aspects of the research design.

Explanations: The Method section in a research plan is designed to provide a clear and detailed account of how the research will be conducted. This includes specifying the research participants, the apparatus and instruments used, the materials needed, and the procedures that will be followed. Therefore, all the above elements are typically included in the Method section.

Option Analysis:

Option A: The research participants are indeed specified in the Method section.
Option B: The apparatus, instruments, and materials are also detailed in the Method section.
Option C: The planned research procedures are outlined in the Method section.
Option D: Since all the above elements are included, this is the correct answer.
