1014. The denominator (bottom) of the z-score formula is

Correct Answer: Correct answer is: (A) The standard deviation.

Exam Relevance: AP Statistics, GRE Quantitative, GMAT Quantitative

Difficulty: Easy

Concept notes: The z-score formula is used to standardize a raw score by subtracting the mean and dividing by the standard deviation.

Common Mistakes: Students often confuse the z-score formula with other statistical formulas, such as the formula for the mean or the range.

Explanations: The z-score formula is given by \( z = \frac{(X - \mu)}{\sigma} \), where \( X \) is the raw score, \( \mu \) is the mean, and \( \sigma \) is the standard deviation. The denominator in this formula is the standard deviation, which standardizes the score relative to the distribution's spread.

Option Analysis:

Option A: Correct. The standard deviation is the denominator in the z-score formula.
Option B: Incorrect. The difference between a score and the mean is the numerator in the z-score formula.
Option C: Incorrect. The range is not part of the z-score formula.
Option D: Incorrect. The mean is subtracted from the score in the numerator of the z-score formula.

1015. Emma and Priscilla made a 100 on their tests.What is the antecedent for their?

Correct Answer: Correct answer is: (C) Emma and Priscilla.

Exam Relevance: SAT, ACT, TOEFL, IELTS

Difficulty: Easy

Concept notes: The antecedent of a pronoun is the noun or noun phrase to which the pronoun refers.

Common Mistakes: Students may mistakenly think the antecedent is the object of the sentence, such as "tests," rather than the subject.

Explanations: In the sentence "Emma and Priscilla made a 100 on their tests," the pronoun "their" refers to Emma and Priscilla. The subject of the sentence is "Emma and Priscilla," making them the antecedent for the pronoun "their."

Option Analysis:

Option A: Incorrect because "tests" is the object of the sentence, not the antecedent for "their."
Option B: Incorrect because "Emma" alone is not the complete antecedent; it must include "Priscilla" as well.
Option C: Correct because "Emma and Priscilla" is the subject and the complete antecedent for "their."
Option D: Incorrect because "Priscilla" alone is not the complete antecedent; it must include "Emma" as well.

Correct Answer: Correct answer is: (C) Cross-sectional studies.

Exam Relevance: AP Psychology, IB Psychology, A-Level Psychology

Difficulty: Moderate

Concept notes: Cross-sectional studies involve observing and comparing different groups at a single point in time.

Common Mistakes: Students may confuse cross-sectional studies with longitudinal studies, which track the same individuals over time.

Explanations: The example of comparing the heights of 9-year-old children to 7-year-old children at a single point in time is a cross-sectional study. This type of study compares different age groups simultaneously, rather than following the same individuals over time.

Option Analysis:

Option A: Experimental studies involve manipulating variables to observe effects, which is not the case here.
Option B: Case studies focus on detailed examination of a single individual or small group, not comparing different age groups.
Option C: Cross-sectional studies compare different groups at one point in time, fitting the example given.
Option D: Vertical studies, or longitudinal studies, track the same individuals over time, which is not the case here.

Mnemonic: Cross-Sectional: Compare Different Groups, Same Time

1017. A factorial design is one in which.....

Correct Answer: Correct answer is: (C) Two or more independent variables are simultaneously studied to determine their independent and interactive effects on the dependent variable.

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

Difficulty: Moderate

Concept notes: A factorial design involves studying the effects of multiple independent variables on a dependent variable, including both their individual effects and their interactions.

Common Mistakes: Students may mistakenly believe that a factorial design only involves two independent variables, or that it only studies the independent effects without considering interactions.

Explanations: A factorial design is a type of experimental design where two or more independent variables are manipulated simultaneously to examine their individual and combined effects on the dependent variable. This allows researchers to understand not only how each independent variable affects the dependent variable but also how the variables interact with each other to influence the outcome.

Option Analysis:

Option A: Incorrect because a factorial design involves more than one independent variable.
Option B: Incorrect because a factorial design can involve more than two independent variables.
Option C: Correct because it accurately describes the nature of a factorial design.
Option D: Incorrect because factorial designs study independent variables, not dependent variables.

1018. When a researcher checks the genuineness and authenticity of the source material, it is known as

Correct Answer: Correct answer is: (D) External criticism.

Exam Relevance: PhD Qualifying Exams, Research Methodology Exams, Historical Studies Exams

Difficulty: Moderate

Concept notes: External criticism involves evaluating the authenticity and reliability of source material.

Common Mistakes: Students may confuse external criticism with internal consistency, which focuses on the coherence within the source material itself.

Explanations: External criticism is the process of assessing the genuineness and authenticity of the source material. It involves verifying the credibility of the source, checking for any alterations or forgeries, and ensuring the material has not been tampered with. This is distinct from internal consistency, which examines the internal coherence of the source material.

Option Analysis:

Option A: Internal consistency refers to the coherence within the source material, not the authenticity of the source itself.
Option B: Concurrent validity is a measure of how well a test correlates with another established test, not related to source material authenticity.
Option C: External validity refers to the generalizability of research findings, not the authenticity of source material.
Option D: External criticism is the correct term for evaluating the authenticity and reliability of source material.

1019. One major issue with the Milgram obedience study and with Watson's early conditioning experiments is that ..... would not have been required because the APA Code of Ethics did not exist.

1020. There are three basic approaches that people tend to adopt when considering ethical issues in research. Which one of the following is not one of the approaches?

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

Exam Relevance: Philosophy exams, Ethics exams, Research Methodology exams

Difficulty: Moderate

Concept notes: Ethical approaches in research include ethical skepticism, utilitarianism, and deontology. Ontology is not an ethical approach but rather a branch of philosophy concerned with the nature of being and existence.

Common Mistakes: Students may confuse ontology with ethical theories because both are philosophical concepts.

Explanations: Ethical skepticism questions the possibility of objective moral knowledge, utilitarianism focuses on the consequences of actions, and deontology emphasizes duty and rules. Ontology, however, deals with the study of existence and is not an ethical approach.

Option Analysis:

Option A: Ethical skepticism is a valid ethical approach that questions the existence of objective moral truths.
Option B: Utilitarianism is a valid ethical approach that evaluates actions based on their consequences.
Option C: Ontology is not an ethical approach but a branch of philosophy concerned with the nature of existence.
Option D: Deontology is a valid ethical approach that emphasizes adherence to rules and duties.
