1462. The sum of deviations taken from actual arithmetic mean is

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

Exam Relevance: GRE, GMAT, CAT, SAT

Difficulty: Easy

Concept notes: The sum of deviations from the arithmetic mean is always zero because the arithmetic mean is the balancing point of the data set.

Common Mistakes: Students often confuse the sum of deviations with the sum of squared deviations, which is not zero.

Explanations: The arithmetic mean is the central point of a data set where the sum of the deviations (differences) of each data point from the mean is zero. This is because the mean balances the positive and negative deviations, making their sum zero.

1464. Which of the following is not a way of assessing the trust worthiness of qualitative research?

Correct Answer: Correct answer is: (B) Accessibility.

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

Difficulty: Moderate

Concept notes: In qualitative research, trustworthiness is assessed through criteria such as dependability, credibility, and transferability. Accessibility is not a standard criterion for assessing the trustworthiness of qualitative research.

Common Mistakes: Students may confuse accessibility with credibility, as both terms relate to the quality and reliability of research findings.

Explanations: Dependability refers to the consistency and stability of the research findings over time. Credibility involves the accuracy and truthfulness of the data, ensuring that the findings are a true representation of the participants' experiences. Transferability assesses the extent to which the findings can be applied to other contexts. Accessibility, however, pertains to the ease with which the research can be understood and accessed by others, which is not directly related to the trustworthiness of the research.

Option Analysis:

Option A: Dependability is a criterion for assessing the trustworthiness of qualitative research, as it ensures consistency and stability of findings.
Option B: Accessibility is not a criterion for assessing the trustworthiness of qualitative research, as it pertains to the ease of understanding and accessing the research, not its reliability or validity.
Option C: Credibility is a criterion for assessing the trustworthiness of qualitative research, as it ensures the accuracy and truthfulness of the data.
Option D: Transferability is a criterion for assessing the trustworthiness of qualitative research, as it evaluates the applicability of findings to other contexts.

Correct Answer: Correct answer is: (A) Simple Random.

Exam Relevance: AP Statistics, GRE, GMAT

Difficulty: Easy

Concept notes: Simple random sampling is a method where every possible group of units of the required size has an equal chance of being selected as the sample.

Common Mistakes: Students may confuse simple random sampling with other sampling methods, such as stratified or cluster sampling, which do not ensure that every possible group has an equal chance of being selected.

Explanations: In simple random sampling, each unit in the population has an equal probability of being chosen, and every possible sample of the required size has the same chance of being selected. This ensures that the sample is representative of the population and unbiased.

Option Analysis:

Option A: Correct. Simple random sampling ensures that every possible group of units has the same chance of being selected.
Option B: Incorrect. "Thoughtful" is not a recognized sampling method.
Option C: Incorrect. "Typical" is not a recognized sampling method.
Option D: Incorrect. "Proportional" sampling methods, such as stratified sampling, do not ensure that every possible group has the same chance of being selected.

1466. If the population on which a study is based is such that all its units can be reached, it is termed as

Correct Answer: Correct answer is: (B) Accessible population.

Exam Relevance: GRE, GMAT, Research Methods Exams

Difficulty: Easy

Concept notes: An accessible population refers to a population where all units can be reached and included in a study.

Common Mistakes: Students may confuse accessible population with target population, which refers to the entire group of interest, not necessarily all of which can be reached.

Explanations: The term "accessible population" is used when all units of the population can be reached and included in a study. This means that there are no practical or logistical barriers preventing the researcher from accessing every unit in the population. Therefore, the correct answer is "Accessible population."

Option Analysis:

Option A: Heterogeneous population refers to a population with diverse characteristics, not necessarily one that can be fully reached.
Option B: Accessible population correctly describes a population where all units can be reached.
Option C: Target population refers to the entire group of interest, which may not be fully accessible.
Option D: Homogeneous population refers to a population with similar characteristics, not necessarily one that can be fully reached.

Mnemonic: Accessible = All can be reached

1467. What is the primary objective of education research that studies a phenomenon about which little is known?

Correct Answer: Correct answer is: (D) To understand.

Exam Relevance: PhD Qualifying Exams, Research Methodology Exams, Educational Psychology Exams

Difficulty: Moderate

Concept notes: The primary objective of education research that studies a phenomenon about which little is known is to understand the phenomenon.

Common Mistakes: Students may confuse the objective of understanding with predicting or describing the phenomenon, which are secondary goals in the initial stages of research.

Explanations: When little is known about a phenomenon, the primary goal of research is to understand the underlying mechanisms, characteristics, and context of the phenomenon. This foundational understanding is crucial before moving on to more complex objectives such as prediction or integration.

Option Analysis:

Option A: Describing a phenomenon is important but is not the primary objective when little is known about it. Understanding comes first.
Option B: Predicting a phenomenon requires a significant amount of prior knowledge and understanding, which is not available when little is known about the phenomenon.
Option C: Integrating knowledge is a later stage in research, after understanding and describing the phenomenon.
Option D: Understanding the phenomenon is the primary objective when little is known about it, as it forms the basis for further research and analysis.

Difficulty: Moderate

Concept notes: Objectivity in research refers to the ability of a study to accurately reflect or represent reality without bias or distortion.

Common Mistakes: Students may confuse objectivity with methodological sophistication or correct judgment of truth, which are related but distinct concepts.

Explanations: Objectivity in research is about ensuring that the findings of a study are consistent with the real-world phenomena being studied. This means that the research methods and data collection techniques should be designed to minimize bias and ensure that the results accurately reflect the true state of affairs.

Option Analysis:

Option A: Correct judgment of truth is related to objectivity but does not fully capture the concept of consistency with reality.
Option B: Methodological sophistication is important for good research but does not directly address the concept of objectivity.
Option C: Research-researcher agreement is a measure of reliability, not objectivity.
Option D: Finding consistency with reality is the correct definition of objectivity in research.
