7. With which one of the following techniques communality is associated?

Correct Answer: Correct answer is: (C) Factor analysis.

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

Difficulty: Moderate

Concept notes: Communality in quantitative research refers to the proportion of variance in a variable that is accounted for by a set of factors. It is a key concept in factor analysis, which is a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved variables called factors.

Common Mistakes: A common misunderstanding is that communality is related to other techniques such as SWOT analysis or univariate analysis, which do not involve the concept of shared variance among variables.

Explanations: Communality is associated with factor analysis because it measures the extent to which a variable is explained by the common factors identified in the analysis. Factor analysis aims to reduce the dimensionality of a dataset by identifying underlying factors that explain the correlations among observed variables. The communality of a variable is the sum of the squared loadings of that variable on all the factors, representing the proportion of the variable's variance that is explained by the factors.

Option Analysis:

Option A: Case studies are qualitative research methods that involve an in-depth examination of a particular case or situation. They do not involve the concept of communality.
Option B: SWOT analysis is a strategic planning tool used to evaluate the strengths, weaknesses, opportunities, and threats of a project or business. It does not involve the concept of communality.
Option C: Factor analysis is a statistical method used to identify underlying factors that explain the correlations among observed variables. Communality is a key concept in factor analysis, representing the proportion of variance in a variable that is explained by the factors.
Option D: Univariate analysis involves the examination of a single variable at a time and does not involve the concept of communality.
