762. Quantitative research has been criticized because

Correct Answer: Correct answer is: (B) The measurement process suggests a spurious and artificial sense of accuracy.

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

Difficulty: Moderate

Concept notes: Quantitative research often involves precise measurements and statistical analysis, which can give the impression of high accuracy. However, this precision can sometimes be misleading, as the methods used may not fully capture the complexity of real-world phenomena.

Common Mistakes: Students may mistakenly believe that quantitative research is inherently more accurate and reliable than qualitative research, overlooking the potential for artificial precision.

Explanations: Quantitative research relies heavily on numerical data and statistical methods, which can create a false sense of precision. This artificial accuracy can be misleading because the methods used may not fully account for the nuances and complexities of the real-world phenomena being studied. Thus, the measurement process in quantitative research can suggest a level of accuracy that may not be truly reflective of the situation.

Option Analysis:

Option A: This option is incorrect because the reliance on instruments and procedures in quantitative research does not necessarily increase ecological validity. Ecological validity refers to the extent to which research findings can be generalized to real-world settings.
Option B: This option is correct because the measurement process in quantitative research can suggest a spurious and artificial sense of accuracy, which is a valid criticism of the method.
Option C: This option is incorrect because quantitative research does not necessarily underestimate the similarities between objects in the natural and social worlds. It can provide valuable insights into these similarities through statistical analysis.
Option D: This option is incorrect because quantitative research does have validity, although it can be criticized for certain limitations.

763. What is the name of an unknown variable that correlates with the independent variable and explains the outcome of the experiment in the same way as the specified independent variable does?

Correct Answer: Correct answer is: (A) A confounded variable.

Exam Relevance: AP Psychology, GRE Psychology, MCAT

Difficulty: Moderate

Concept notes: A confounded variable is a variable that correlates with both the independent and dependent variables, potentially leading to misleading conclusions about the relationship between the independent and dependent variables.

Common Mistakes: Students often confuse confounded variables with extraneous variables, which are variables that can affect the outcome but are not of primary interest in the study.

Explanations: A confounded variable is a variable that correlates with both the independent and dependent variables, potentially leading to misleading conclusions about the relationship between the independent and dependent variables. This means that the confounded variable can explain the outcome in the same way as the independent variable, making it difficult to determine the true effect of the independent variable.

Option Analysis:

Option A: Correct. A confounded variable is a variable that correlates with both the independent and dependent variables, potentially leading to misleading conclusions about the relationship between the independent and dependent variables.
Option B: Incorrect. An extraneous variable is a variable that can affect the outcome but is not of primary interest in the study. It does not necessarily correlate with the independent variable.
Option C: Incorrect. A controlled variable is a variable that is kept constant to prevent it from influencing the outcome of the experiment. It does not correlate with the independent variable.
Option D: Incorrect. An implicit variable is not a standard term in experimental design and does not describe a variable that correlates with both the independent and dependent variables.

764. What is a questionnaire?

Correct Answer: Correct answer is: (B) A set of printed or written questions with a choice of answers.

Exam Relevance: AP Psychology, SAT, ACT

Difficulty: Easy

Concept notes: A questionnaire is a set of printed or written questions designed to gather information from respondents.

Common Mistakes: Students may confuse a questionnaire with a focus group or an interview, which involve more interactive and open-ended discussions.

Explanations: A questionnaire is specifically designed to gather information through a set of predefined questions, often with multiple-choice answers. This format allows for standardized data collection and analysis.

Option Analysis:

Option A: This describes a focus group, not a questionnaire.
Option B: This correctly defines a questionnaire as a set of printed or written questions with a choice of answers.
Option C: This describes an interview, not a questionnaire.
Option D: This describes observation, not a questionnaire.

765. Which section of the research paper contains the purpose statement and the research questions?

Correct Answer: Correct answer is: (B) Statement of the problem.

Exam Relevance: GRE, GMAT, Research Methodology Exams

Difficulty: Moderate

Concept notes: The statement of the problem section in a research paper typically includes the purpose statement and the research questions.

Common Mistakes: Students may confuse the statement of the problem with the background of the study, which provides context and background information rather than the specific purpose and questions.

Explanations: The statement of the problem section is where the researcher clearly defines the purpose of the study and outlines the specific research questions or hypotheses. This section is crucial as it sets the stage for the entire research, making it the appropriate place for the purpose statement and research questions.

Option Analysis:

Option A: The overview section typically provides a brief summary of the entire research paper, not the specific purpose and questions.
Option B: The statement of the problem section includes the purpose statement and research questions, making it the correct choice.
Option C: The significance of the study section explains why the research is important and relevant, but does not include the purpose statement or research questions.
Option D: The background of the study section provides context and background information, but not the specific purpose and questions.

766. This sample consists of units of the population that chose to respond.

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

Exam Relevance: AP Statistics, GRE, GMAT, Undergraduate Statistics Exams

Difficulty: Moderate

Concept notes: A volunteer sample is a type of non-probability sampling where participants choose to be part of the study.

Common Mistakes: Students may confuse volunteer samples with mandatory or census samples, which involve different selection methods.

Explanations: A volunteer sample consists of units of the population that choose to respond. This aligns with the definition of a volunteer sample, where participants self-select into the study. The other options do not fit this description: mandatory samples are required by law, census samples include every member of the population, and unbiased samples are typically probability samples where every unit has an equal chance of being selected.

Option Analysis:

Option A: Mandatory samples are required by law or regulation, not by voluntary participation.
Option B: Census samples include every member of the population, not just those who choose to respond.
Option C: Volunteer samples consist of participants who choose to respond, fitting the description given.
Option D: Unbiased samples are typically probability samples where every unit has an equal chance of being selected, not self-selected.

Mnemonic: VOL = Volunteer, Opt-in, Lure

767. The control group

Correct Answer: Correct answer is: (D) Does not have the independent variable and is used for comparison.

Exam Relevance: AP Biology, AP Chemistry, IB Biology, IB Chemistry

Difficulty: Easy

Concept notes: The control group in an experiment is the group that does not receive the experimental treatment and is used as a baseline for comparison.

Common Mistakes: Students often confuse the control group with the experimental group, which is the group that receives the treatment.

Explanations: The control group does not have the independent variable, which is the variable that is manipulated in the experiment. This group serves as a standard for comparison to determine the effect of the independent variable on the dependent variable.

Option Analysis:

Option A: This is incorrect because the parts of the experiment that are kept the same are known as the controlled variables, not the control group.
Option B: This is incorrect because data is typically collected from both the control group and the experimental group.
Option C: This is incorrect because the group that has the independent variable changed is the experimental group, not the control group.
Option D: This is correct because the control group does not have the independent variable and is used for comparison.

Mnemonic: Control = Constant, Compare

768. A study on new technology integration collects ratings-scale questionnaire data from a middle-school's faculty for the quantitative phase. Evaluation of the data from the quantitative phase leads to in-depth observation of two of the middle school faculty for the qualitative phase that takes place two months later.

Correct Answer: Correct answer is: (B) Nested sequential.

Exam Relevance: Research Methods in Psychology, Social Science Research Methods, Educational Research Methods

Difficulty: Moderate

Concept notes: In nested sequential design, the qualitative phase is embedded within the quantitative phase, often using the quantitative data to guide the selection of participants for the qualitative phase.

Common Mistakes: Students may confuse nested sequential with parallel concurrent, where both phases occur simultaneously, or with identical sequential, where the qualitative phase is conducted after the quantitative phase without using the quantitative data to guide the qualitative phase.

Explanations: The study first collects quantitative data from the entire faculty through a ratings-scale questionnaire. This quantitative phase is followed by a qualitative phase where two faculty members are selected for in-depth observation based on the initial quantitative data. This approach aligns with the nested sequential design, where the qualitative phase is nested within the quantitative phase, using the quantitative data to guide the qualitative phase.

Option Analysis:

Option A: Identical sequential involves conducting the qualitative phase after the quantitative phase without using the quantitative data to guide the qualitative phase.
Option B: Nested sequential involves using the quantitative data to guide the selection of participants for the qualitative phase, which is the case here.
Option C: Multilevel concurrent involves collecting both quantitative and qualitative data simultaneously at multiple levels, which is not the case here.
Option D: Parallel concurrent involves collecting both quantitative and qualitative data simultaneously, which is not the case here.

Mnemonic: Nested = Nested within, using quantitative to guide qualitative.

769. Suspense and tension starts to build during the.....

Correct Answer: Correct answer is: (B) Rising action.

Exam Relevance: SAT, ACT, AP English Literature

Difficulty: Moderate

Concept notes: In a narrative structure, the rising action is the part of the story where the main conflict begins to develop and the tension starts to build.

Common Mistakes: Students may confuse the rising action with the exposition, where the setting and characters are introduced, or the falling action, where the conflict begins to resolve.

Explanations: The rising action is the phase in a story where the main conflict is introduced and developed, leading to increased suspense and tension. This phase is crucial for engaging the audience and building up to the climax.

Option Analysis:

Option A: The exposition introduces the setting and characters, not the tension.
Option B: The rising action is where the conflict develops and tension builds.
Option C: The falling action occurs after the climax, where the tension begins to resolve.
Option D: The resolution is the conclusion of the story, where all conflicts are resolved.

Mnemonic: Rising Action: R.A. - Rising Anticipation

770. A disadvantage of ..... is that the data is limited to only answering the question(s) asked. These limitations lead to biases, ambiguous conclusions, and low participation rates among research populations.

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

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

Difficulty: Moderate

Concept notes: Surveys are a method of data collection where participants are asked a set of predefined questions. The data collected is limited to the specific questions asked, which can lead to biases, ambiguous conclusions, and low participation rates.

Common Mistakes: Students may confuse the limitations of surveys with those of other data collection methods, such as observations or experiments.

Explanations: Surveys are limited to the specific questions asked, which can result in biases and ambiguous conclusions. Additionally, low participation rates can further limit the data's representativeness and reliability. This makes surveys a suitable answer for the given statement.

Option Analysis:

Option A: Surveys are limited to the specific questions asked, leading to biases, ambiguous conclusions, and low participation rates.
Option B: Observations do not have the same limitations as surveys since they involve direct observation of behavior or phenomena.
Option C: Correlations measure the relationship between variables but do not have the same limitations as surveys in terms of question specificity.
Option D: Experiments involve manipulating variables to establish cause-and-effect relationships and do not have the same limitations as surveys.
