1091. In data analysis of the grounded theory approach, the step which focuses on the main idea, developing the story line, and finalizing the theory is called.....

Correct Answer: Correct answer is: (C) Selective coding.

Exam Relevance: Qualitative Research Methods, Social Science Research, PhD Comprehensive Exams

Difficulty: Moderate

Concept notes: Selective coding is the final stage of data analysis in the grounded theory approach, where the main idea is identified, the story line is developed, and the theory is finalized.

Common Mistakes: Students often confuse selective coding with axial coding, which is the stage where categories are integrated and relationships between them are established.

Explanations: Selective coding is the stage in grounded theory where the main idea or core category is identified, and the story line of the theory is developed. This stage involves integrating the categories and subcategories identified in the earlier stages (open and axial coding) to form a coherent theory. The focus is on refining and finalizing the theory by identifying the central theme and how it relates to other categories.

Option Analysis:

Option A: Theoretical saturation is the point at which no new information or categories are emerging from the data, not the stage of developing the story line.
Option B: Axial coding involves integrating categories and establishing relationships between them, but it does not focus on finalizing the theory.
Option C: Selective coding is the correct answer as it involves identifying the main idea, developing the story line, and finalizing the theory.
Option D: Open coding is the initial stage of data analysis where data is broken down into discrete parts and initial codes are assigned, not the stage of finalizing the theory.

1092. Karl Pearson's coefficient of skewness

Correct Answer: Correct answer is: (C) Can be both positive and negative.

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

Difficulty: Moderate

Concept notes: Karl Pearson's coefficient of skewness measures the asymmetry of a distribution. It can be positive, negative, or zero, depending on the shape of the distribution.

Common Mistakes: Students often mistakenly believe that skewness is always positive or negative, not considering the possibility of a symmetrical distribution where skewness is zero.

Explanations: Karl Pearson's coefficient of skewness is calculated as the difference between the mean and the mode, divided by the standard deviation. This formula allows for the skewness to be positive if the mean is greater than the mode, negative if the mean is less than the mode, and zero if the mean equals the mode. Therefore, the skewness can be both positive and negative, depending on the distribution's shape.

Option Analysis:

Option A: Incorrect because skewness can be negative or zero.
Option B: Incorrect because skewness can be positive or zero.
Option C: Correct because skewness can be both positive and negative.
Option D: Incorrect because skewness can be zero.

1093. Which of the following functions is performed by the Ordinal scale?

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

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

Difficulty: Easy

Concept notes: The ordinal scale is a type of measurement scale that allows ranking or ordering of items based on a specific criterion.

Common Mistakes: Students often confuse the ordinal scale with the interval or ratio scales, which also measure distance or unique origin.

Explanations: The ordinal scale is used to rank or order items, but it does not provide information about the magnitude of differences between the ranks. Therefore, the function performed by the ordinal scale is to order items.

Option Analysis:

Option A: Distance is not a function of the ordinal scale. It is more relevant to interval or ratio scales.
Option B: Order is the correct function of the ordinal scale, as it ranks items without specifying the magnitude of differences between them.
Option C: Categorize is a function of the nominal scale, not the ordinal scale.
Option D: Unique origin is a function of the ratio scale, not the ordinal scale.

Mnemonic: ORD - Order, Rank, Differentiate

1094. Which of the following is not a common element of a research proposal and a research report?

Correct Answer: Correct answer is: (B) Implications for further research.

Exam Relevance: PhD Qualifying Exams, Research Methodology Exams

Difficulty: Moderate

Concept notes: Research proposals and research reports share several common elements, but implications for further research are typically found in research reports rather than proposals.

Common Mistakes: Students may confuse the purpose of a research proposal with that of a research report, leading to the incorrect assumption that both documents should contain the same elements.

Explanations: Research proposals outline the objectives, hypotheses, and sources of information/data, and they often reference previous research to justify the need for the proposed study. However, implications for further research are generally included in research reports, which summarize the findings and suggest areas for future investigation. Therefore, implications for further research are not a common element of a research proposal.

Option Analysis:

Option A: Objectives and hypotheses are common in both research proposals and research reports.
Option B: Implications for further research are typically found in research reports, not in proposals.
Option C: References to previous research are common in both research proposals and research reports.
Option D: Sources of information/data are common in both research proposals and research reports.

1095. GLM refers to which of the following?

Correct Answer: Correct answer is: (C) General Linear Model.

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

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

Exam Relevance: GRE, MCAT, LSAT

Difficulty: Moderate

Concept notes: Theories are often subject to revision and can be challenged based on new evidence or perspectives.

Common Mistakes: Students may mistakenly believe that theories are always indisputable because they are widely accepted.

Explanations: Theories are provisional and subject to change based on new evidence or interpretations. They are not considered indisputable because they can be revised or replaced as our understanding evolves.

Option Analysis:

Option A: Theories can be localized in their application or scope.
Option B: Theories are often provisional and subject to revision.
Option C: Theories are not considered indisputable as they can be challenged and revised.
Option D: This option is not applicable as one of the other options is correct.

1097. Which one of the following is an indication of the quality of a research journal?

Correct Answer: Correct answer is: (B) Impact factor.

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

Difficulty: Moderate

Concept notes: The impact factor is a measure reflecting the average number of citations to recent articles published in a journal. It is commonly used as an indicator of the quality and influence of a research journal.

Common Mistakes: Students may confuse the impact factor with other metrics like the h-index or g-index, which measure different aspects of an author's or journal's performance.

Explanations: The impact factor is a widely recognized metric for evaluating the quality and influence of a research journal. It is calculated based on the average number of citations received by articles published in the journal over a specific period, typically the previous two years. This metric provides a quantitative measure of the journal's impact and is often used by researchers, institutions, and funding bodies to assess the quality of a journal.

Option Analysis:

Option A: The I10-index is a metric used by Google Scholar to measure the number of publications with at least 10 citations. It is not a direct measure of journal quality.
Option B: The impact factor is a widely recognized metric for evaluating the quality and influence of a research journal.
Option C: The g-index is a measure of productivity and impact of a scientist or a journal, but it is not as commonly used as the impact factor for evaluating journal quality.
Option D: The h-index is a measure of both the productivity and citation impact of a scientist or a journal, but it is not specifically used to indicate the quality of a research journal.

Mnemonic: IF for Impact Factor, think "Influential Factor."

1098. A scientist can generate new and original ideas.

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

Exam Relevance: SAT, ACT, AP Psychology

Difficulty: Easy

Concept notes: Creativity is the ability to generate new and original ideas.

Common Mistakes: Students may confuse creativity with curiosity, which is the desire to learn and understand new things.

Explanations: A scientist who can generate new and original ideas demonstrates creativity. This ability is crucial for innovation and problem-solving in scientific research.

Option Analysis:

Option A: Curiosity is the desire to learn and understand new things, not the ability to generate new ideas.
Option B: Creativity is the ability to generate new and original ideas, which aligns with the statement.
Option C: Objectivity is the ability to judge or consider something without bias, not the ability to generate new ideas.
Option D: Honesty is the quality of being truthful and sincere, not the ability to generate new ideas.

1099. Problems occurring in a narrowly defined environment-such as a single eighth-grade classroom-are best handled under which scope of action research?

Correct Answer: Correct answer is: (A) Individual action research.

Exam Relevance: AP Psychology, AP Sociology, Educational Psychology exams
