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

Exam Relevance: SAT, ACT, AP English Literature

Difficulty: Easy

Concept notes: The setting in a story refers to the time and place where the events occur.

Common Mistakes: Students may confuse the setting with the plot, which is the sequence of events in the story.

Explanations: The setting in literature is the context in which the story takes place, including the time period and geographical location. It provides the backdrop against which the characters and events unfold.

Option Analysis:

Option A: Tone refers to the author's attitude toward the subject or the audience, not the time and place of the story.
Option B: Plot refers to the sequence of events in the story, not the time and place.
Option C: Setting refers to the time and place where the story occurs, which is the correct answer.
Option D: Voice refers to the perspective from which the story is told, not the time and place.

Mnemonic: S-T-E-T-T-I-N-G: Setting Tells Everything, Time and Place in Narrative.

692. In..... the main purpose is to formulate a problem for more precise investigation

Correct Answer: Correct answer is: (A) Exploratory or Formulative study.

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

Difficulty: Moderate

Concept notes: Exploratory or Formulative studies aim to define and clarify the problem for further investigation.

Common Mistakes: Students may confuse exploratory studies with descriptive studies, which aim to describe characteristics of a population or phenomenon.

Explanations: The main purpose of an exploratory or formulative study is to formulate a problem for more precise investigation. This type of study is often used when the research problem is not clearly defined and requires initial exploration to identify key issues and variables. It is not focused on describing characteristics (descriptive study) or diagnosing underlying causes (diagnostic study).

Option Analysis:

Option A: Correct. Exploratory or formulative studies aim to define and clarify the problem for further investigation.
Option B: Incorrect. Descriptive studies aim to describe characteristics of a population or phenomenon, not to formulate a problem.
Option C: Incorrect. Diagnostic studies aim to identify the underlying causes of a problem, not to formulate the problem itself.
Option D: Incorrect. This option is not applicable as the correct answer is provided in Option A.

Mnemonic: E for Explore, F for Formulate

693. What is the first stage of the research process?

Correct Answer: Correct answer is: (D) Define the research problem.

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

Difficulty: Easy

Concept notes: The first stage of the research process involves clearly defining the research problem or question that needs to be addressed.

Common Mistakes: Students often mistakenly believe that data collection is the first step, but it is actually the second stage after defining the research problem.

Explanations: Defining the research problem is the initial and critical step in the research process. It sets the foundation for the entire study, guiding the subsequent stages such as data collection, analysis, and reporting. Without a well-defined problem, the research may lack direction and purpose.

Option Analysis:

Option A: Collecting and analyzing data is a subsequent step, not the first stage.
Option B: Developing and implementing the research plan comes after defining the problem.
Option C: Reporting the findings is the final stage of the research process.
Option D: Defining the research problem is the first stage.

694. A sequencing effect that occurs when performance in one treatment condition is influenced by participation in a prior treatment condition is known as.....

Correct Answer: Correct answer is: (A) Carryover effect.

Exam Relevance: Psychology exams, Research Methods exams, Experimental Design exams

Difficulty: Moderate

Concept notes: The carryover effect occurs when the effects of one treatment condition persist into the next treatment condition, influencing the results.

Common Mistakes: Students may confuse the carryover effect with the order effect, which refers to the influence of the sequence of treatments on performance.

Explanations: The carryover effect is specifically defined as the influence of participation in a prior treatment condition on performance in a subsequent treatment condition. This effect can confound the results of an experiment if not properly controlled.

Option Analysis:

Option A: Correct. The carryover effect is the influence of a prior treatment condition on a subsequent treatment condition.
Option B: Incorrect. Counterbalancing is a technique used to control for carryover effects, not the effect itself.
Option C: Incorrect. Order effect refers to the influence of the sequence of treatments on performance, not the persistence of effects from one treatment to another.
Option D: Incorrect. Treatment effect refers to the impact of a specific treatment, not the influence of a prior treatment on a subsequent one.

695. In the three dimension of philosophy. The study of value has been carried out under

Correct Answer: Correct answer is: (D) None of the above.

Exam Relevance: Philosophy exams, Ethics exams, Aesthetics exams

Difficulty: Moderate

Concept notes: The study of value in philosophy is typically categorized under the branch known as axiology, which includes ethics and aesthetics. Epistemology, modal logic, and temporal logic do not specifically cover the study of value.

Common Mistakes: Students may mistakenly believe that the study of value falls under epistemology, which is concerned with knowledge and belief, rather than axiology, which deals with value.

Explanations: The study of value in philosophy is primarily conducted under the branch of axiology, which includes ethics and aesthetics. Epistemology, which is the study of knowledge and belief, does not specifically address the study of value. Modal logic and temporal logic are branches of logic that deal with possibility and necessity, and time, respectively, and do not focus on the study of value. Therefore, the correct answer is "None of the above."

Option Analysis:

Option A: Epistemology is the study of knowledge and belief, not value.
Option B: Modal logic deals with possibility and necessity, not value.
Option C: Temporal logic deals with time, not value.
Option D: None of the above is correct as the study of value is conducted under axiology, not the listed options.

Mnemonic: Axiology: A for Aesthetics, E for Ethics

696. Sampling error decreases with the

Correct Answer: Correct answer is: (B) Increase in sample size.

Exam Relevance: AP Statistics, GRE, GMAT, MCAT

Difficulty: Moderate

Concept notes: Sampling error is the difference between a sample statistic and the actual population parameter. It decreases as the sample size increases because larger samples tend to more accurately represent the population.

Common Mistakes: Students often confuse the relationship between sample size and sampling error, thinking that smaller samples might be more accurate.

Explanations: Sampling error decreases with an increase in sample size because larger samples are more likely to reflect the true characteristics of the population. This is due to the law of large numbers, which states that as the sample size increases, the sample mean approaches the population mean.

Option Analysis:

Option A: Decrease in sample size would increase sampling error, not decrease it.
Option B: Increase in sample size reduces sampling error, making this the correct answer.
Option C: Process of randomization helps reduce bias but does not directly decrease sampling error.
Option D: Process of analysis does not directly affect sampling error.

697. What Z-value would be used to set up a confidence interval at the 95 percent confidence level when the sample size is 200?

Correct Answer: Correct answer is: (C) 1.96.

Exam Relevance: AP Statistics, GRE, GMAT, MBA Entrance Exams

Difficulty: Moderate

Concept notes: The Z-value for a 95% confidence interval is a standard value used in statistics to determine the margin of error for a given sample size.

Common Mistakes: Students often confuse the Z-value for different confidence levels, such as 90% or 99%, which have different Z-values.

Explanations: The Z-value for a 95% confidence interval is 1.96. This value is derived from the standard normal distribution, where 95% of the area under the curve lies within 1.96 standard deviations from the mean. This Z-value is used to construct confidence intervals for population means when the sample size is large (typically n > 30) and the population standard deviation is known.

Option Analysis:

Option A: 0.01 is not a Z-value for a 95% confidence interval. It is a very small value that might be confused with a significance level (α).
Option B: 2.58 is the Z-value for a 99% confidence interval, not 95%.
Option C: 1.96 is the correct Z-value for a 95% confidence interval.
Option D: 0.05 is a significance level (α) and not a Z-value for a confidence interval.

698. It does not possible or even desirable to rule out the differential effects of all relevant variables by means of experimental control. In such instances psychologists employ controlled conditions by mathematical methods. This is called

Correct Answer: Correct answer is: (D) Statistical Control.

Exam Relevance: AP Psychology, GRE Psychology, Psychology PhD Qualifying Exams

Difficulty: Moderate

Concept notes: Statistical control is a method used in psychological research to account for the influence of extraneous variables that cannot be controlled through experimental means.

Common Mistakes: Students may confuse statistical control with experimental control, which involves physically manipulating or controlling variables in a laboratory setting.

Explanations: Statistical control is the correct answer because it refers to the use of mathematical and statistical techniques to control for the effects of extraneous variables in research. This method is particularly useful when it is not feasible to control all relevant variables through experimental means. By using statistical methods, researchers can adjust for the influence of these variables and isolate the effect of the independent variable on the dependent variable.

Option Analysis:

Option A: Mathematical Control is not a standard term in psychological research.
Option B: Physiological Control refers to the control of biological variables, not statistical methods.
Option C: Psychological Control is not a term used to describe the use of statistical methods in research.
Option D: Statistical Control is the correct term for using mathematical methods to control for extraneous variables.

699. The standard deviation

Correct Answer: Correct answer is: (A) Indicates the average difference between each score in a group and the mean for that group of scores.

Exam Relevance: AP Statistics, GRE, GMAT, SAT

Difficulty: Moderate

Concept notes: The standard deviation is a measure of the dispersion or spread of a set of data points from the mean. It quantifies the average deviation of each score from the mean.

Common Mistakes: Students often confuse standard deviation with other measures of dispersion, such as variance or range, or they may think it measures the skewness of the distribution.

Explanations: The standard deviation is calculated by taking the square root of the variance, which is the average of the squared differences from the mean. This measure indicates how much, on average, each score deviates from the mean. Therefore, it correctly describes the average difference between each score and the mean.

Option Analysis:

Option A: Correct. The standard deviation does indicate the average difference between each score and the mean.
Option B: Incorrect. The standard deviation does not reveal the degree of skewness in a distribution; skewness is a separate measure.
Option C: Incorrect. While the standard deviation is sensitive to extreme values, it does not specifically measure the degree of sensitivity to scores at the extremes.
Option D: Incorrect. The standard deviation is not used to determine whether a data set is positively or negatively skewed; skewness is a different measure.

700. The main character of the story is the.....

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

Exam Relevance: SAT, ACT, AP Literature, IB English

Difficulty: Easy

Concept notes: The protagonist is the main character in a story, around whom the plot revolves.

Common Mistakes: Students may confuse the protagonist with the antagonist, who is the main opposing character.

Explanations: The main character of the story is the protagonist because the protagonist is the central figure whose actions and decisions drive the narrative forward.

Option Analysis:

Option A: Correct, as the protagonist is the main character in a story.
Option B: Incorrect, as the antagonist is the opposing character to the protagonist.
Option C: Incorrect, as the main character is specifically the protagonist, not the antagonist.
Option D: Incorrect, as the main character is the protagonist, not neither.

Mnemonic: Protagonist = Pro-Tag-Onist = Pro-Tag-On = Protagonist is the main character.
