Common Mistakes: Students may confuse conceptualization with planning and designing, which is a later phase involving the detailed setup of the research.

Explanations: Conceptualization involves the initial formation of ideas and the identification of the research problem. It is the first step in the research process, where researchers define the research question and develop a theoretical framework.

Option Analysis:

Option A: Correct. Conceptualization is the initial phase where researchers form an idea about what needs to be studied.
Option B: Incorrect. Planning and designing is a later phase involving the detailed setup of the research.
Option C: Incorrect. Analyzing and interpreting is a phase that occurs after data collection and involves making sense of the data.
Option D: Incorrect. This option is not applicable as the correct answer is provided.

342. What is a Quasi-experiment?

Correct Answer: Correct answer is: (C) Quasi-experiment research involves the manipulation of an independent variable without the random assignment of participants to conditions or orders of conditions.

Exam Relevance: Psychology exams, Research Methods exams

Difficulty: Moderate

Concept notes: Quasi-experiments are a type of research design where the researcher manipulates an independent variable but does not use random assignment to allocate participants to different conditions.

Common Mistakes: Students often confuse quasi-experiments with true experiments, where random assignment is a key component.

Explanations: In a quasi-experiment, the researcher manipulates the independent variable but does not randomly assign participants to conditions. This is a key characteristic that distinguishes quasi-experiments from true experiments. The lack of random assignment can introduce confounding variables, making it more challenging to establish causality.

Option Analysis:

Option A: This describes a double-blind procedure, not a quasi-experiment.
Option B: This describes a placebo-controlled study, not a quasi-experiment.
Option C: This correctly defines a quasi-experiment.
Option D: This describes a field experiment, not a quasi-experiment.

343. The sum of absolute deviations of items is minimum from

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

Exam Relevance: GRE, GMAT, CAT, SAT

Difficulty: Moderate

Concept notes: The median is the value that minimizes the sum of absolute deviations from all other values in a dataset.

Common Mistakes: Students often confuse the median with the mean, which minimizes the sum of squared deviations, not the sum of absolute deviations.

Explanations: The median is the middle value in a dataset when the data is ordered. It is the value that minimizes the sum of absolute deviations from all other values. This is because the median splits the data into two equal halves, ensuring that the sum of deviations on either side is minimized.

Option Analysis:

Option A: The harmonic mean is the reciprocal of the arithmetic mean of the reciprocals of the data. It does not minimize the sum of absolute deviations.
Option B: The mode is the most frequently occurring value in a dataset. It does not necessarily minimize the sum of absolute deviations.
Option C: The median minimizes the sum of absolute deviations from all other values in a dataset.
Option D: The geometric mean is the nth root of the product of n values. It does not minimize the sum of absolute deviations.

Mnemonic: Median Minimizer

344. Assumption of the reality of subjective (personal experience), intersubjective (e.g., languages and cultures), and objective or material realities (e.g., material reality that will be present when humans are long gone such as mountains, oceans, and stars) is part of the ..... of mixed research.

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

Exam Relevance: PhD Qualifying Exams, Research Methodology Exams, Philosophy Exams

Difficulty: Moderate

Concept notes: Ontology is the branch of philosophy that deals with the nature of being, existence, and reality. It concerns itself with questions about what exists and how different entities relate to each other.

Common Mistakes: Students may confuse ontology with epistemology, which is the study of knowledge and belief.

Explanations: The assumption of the reality of subjective, intersubjective, and objective realities is part of ontology because it deals with the nature of existence and reality. Ontology is concerned with what exists and how different types of entities (subjective, intersubjective, and objective) relate to each other in terms of their existence.

Option Analysis:

Option A: Correct. Ontology deals with the nature of existence and reality, which includes the assumption of subjective, intersubjective, and objective realities.
Option B: Incorrect. Epistemology is the study of knowledge and belief, not the nature of existence and reality.
Option C: Incorrect. The correct answer is solely ontology, not a combination of ontology and epistemology.
Option D: Incorrect. The correct answer is ontology, not neither ontology nor epistemology.

345. An experiment is set up to confirm or refute some

Difficulty: Moderate

Concept notes: An experiment is designed to test a hypothesis, which is a proposed explanation for a phenomenon or observation.

Common Mistakes: Students may confuse hypotheses with questions or events, as experiments often start with a question and involve events.

Explanations: An experiment is set up to confirm or refute hypotheses. A hypothesis is a testable statement that can be supported or refuted by experimental data. Experiments are not primarily set up to confirm or refute questions, which are more about seeking information, or events, which are occurrences that happen independently of testing.

Option Analysis:

Option A: Questions are the starting point for experiments but not what experiments directly confirm or refute.
Option B: Hypotheses are testable statements that experiments aim to confirm or refute.
Option C: Enquiry is a process of investigation but not what experiments directly confirm or refute.
Option D: Events are occurrences that experiments do not directly confirm or refute.

Mnemonic: HYP: Hypotheses Yield Proofs

346. Which of the following sampling methods is based on probability?

Correct Answer: Correct answer is: (A) Stratified sampling.

Exam Relevance: AP Statistics, GRE, GMAT

Difficulty: Easy

Concept notes: Stratified sampling is a probability sampling method where the population is divided into subgroups (strata) based on shared characteristics, and samples are randomly selected from each stratum.

Common Mistakes: Students may confuse stratified sampling with other non-probability methods like convenience or judgment sampling, which do not involve random selection.

Explanations: Stratified sampling is based on probability because it involves dividing the population into distinct strata and then randomly selecting samples from each stratum. This ensures that each subgroup is represented in the sample, and the selection process is random, making it a probability sampling method.

Option Analysis:

Option A: Stratified sampling is a probability sampling method because it involves random selection from each stratum.
Option B: Convenience sampling is not a probability method as it relies on easily accessible subjects rather than random selection.
Option C: Judgment sampling is not a probability method as it relies on the researcher's judgment to select subjects.
Option D: Quota sampling is not a probability method as it involves selecting subjects to meet specific quotas rather than random selection.

347. Educational researchers should ..... helpful or relevant information resulting from studies conducted in their professional community.

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

Exam Relevance: GRE, GMAT, Psychology Exams, Management Exams

Difficulty: Easy

Concept notes: A sociogram is a visual representation of social relationships within a group. It is used to study the patterns of interaction and relationships among individuals.

Common Mistakes: Students may confuse the sociogram with other psychological assessment tools, such as vocational interest tests or achievement motivation scales.

Explanations: The sociogram technique is specifically designed to map out and analyze the social interactions and relationships within a group. This makes it a tool for studying human relations, as it helps to understand the dynamics and connections between individuals.

Option Analysis:

Option A: Correct. The sociogram is used to study human relations by mapping out social interactions and relationships within a group.
Option B: Incorrect. Vocational interest is typically assessed through different tools such as interest inventories or career assessments.
Option C: Incorrect. Achievement motivation is usually measured through self-report questionnaires or behavioral assessments, not sociograms.
Option D: Incorrect. Professional competence is often evaluated through performance assessments, skill tests, or job-related tasks, not sociograms.

Mnemonic: Sociogram: Social Connections

349. Electronic collections of information is?

Correct Answer: Correct answer is: (D) Database.

Exam Relevance: Database Management Systems, Computer Science Exams, Information Technology Exams

Difficulty: Moderate

Concept notes: A database is an organized collection of data, often stored and accessed electronically from a computer system.

Explanations: A database is the correct answer because it refers to an organized collection of data that can be electronically stored and accessed. An index is a list of items in a document, a glossary is a list of terms and their definitions, and a source is where information originates. None of these options describe an electronic collection of information as comprehensively as a database does.

Option Analysis:

Option A: An index is a list of items in a document, not an electronic collection of information.
Option B: A glossary is a list of terms and their definitions, not an electronic collection of information.
Option C: A source is where information originates, not an electronic collection of information.
Option D: A database is an organized collection of data that can be electronically stored and accessed, making it the correct answer.

Mnemonic: Data Base = Digital Archive

350. The ..... means success of a method in assessing what is to be assess.

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

Exam Relevance: GRE, MCAT, GMAT

Difficulty: Moderate

Concept notes: Validity refers to the extent to which a method accurately measures what it is intended to measure.

Common Mistakes: Students often confuse validity with reliability, which is about the consistency of the measurement.

Explanations: Validity is the measure of how well a method assesses the intended construct or outcome. It ensures that the method is not only consistent but also accurate in its assessment. Reliability, on the other hand, refers to the consistency of the results, but does not necessarily ensure that the method is measuring the correct construct.

Option Analysis:

Option A: Reliability refers to the consistency of a method, not its accuracy in measuring the intended construct.
Option B: Consistency is related to reliability, not the accuracy of the measurement.
Option C: Validity is the correct term for the success of a method in assessing what is intended to be assessed.
Option D: Feasibility refers to the practicality of implementing a method, not its accuracy in measurement.
