Quiz | Factor Analysis /24 59 Quiz | Factor Analysis 1 / 24 What is the primary objective of factor analysis compared to principal component analysis (PCA)? To maximize the explained variance by the extracted factors To reduce the dimensionality of data To uncover the common causes (factors) of observed variables and their correlations To eliminate unique variance in observed variables 2 / 24 In the context of factor scores, what does a factor score of 0 signify? An object is rated above average on the factor. An object has the highest rating on the factor. An object is rated below average on the factor. An object has an average rating on the factor. 3 / 24 What are factor loadings in factor analysis? The factors themselves Assessment values per person The strength of the correlations between original variables and the factors The number of factors extracted 4 / 24 What does a negative factor score represent in factor analysis? An object is rated above average on the factor. An object is rated below average on the factor. An object has the highest rating on the factor. An object has an average rating on the factor. 5 / 24 What is the first step in conducting a factor analysis? Extracting the factors Determining the factor scores Evaluating the suitability of the data Interpreting the factors 6 / 24 What statement(s) related to the KMO and MSA criterion are correct? MSA assesses the suitability of a single variable. KMO assesses the suitability of the correlation matrix. There is no difference between the two criteria. Both criteria measure the same. 7 / 24 In what step of factor analysis is the user required to decide how many factors are to be extracted? Step 2: Extracting the factors Step 3: Interpreting the factors Step 4: Assessing factor scores Step 1: Checking data suitability 8 / 24 In factor analysis, what do factor loadings (ajq) represent? The variance of the observed variables The sum of the squared factor loadings The correlation between an observed variable and the extracted factor The number of observations (cases) 9 / 24 How is the suitability of data for factor analysis typically evaluated? By conducting a regression analysis By calculating the correlation matrix By assessing inter-item reliability By examining means and standard deviations 10 / 24 Explain why the variable "I have difficulty in imagining Calvé in my mind” has a negative factor loading for factor 1. This must be a mistake. Factor loadings need to be positive. The item is a reverse coded item, and has, thus, a negative factor loading. 11 / 24 What does a high correlation between two variables indicate in factor analysis? They can be combined into a common factor. They should be eliminated from the analysis. They are unsuitable for factor analysis. They are weakly correlated with other variables. 12 / 24 What does the fundamental theorem of factor analysis state? It defines the correlation matrix. It calculates the variance of factors It relates observed data to unobserved factors. It explains how to standardize data. 13 / 24 How are summated scales calculated for factor scores in factor analysis? By taking the sum of the highest factor loadings for each factor By multiplying factor loadings by the number of variables By calculating the mean of the high-loading variables for each factor By using regression analysis on factor loadings 14 / 24 What is the primary purpose of determining factor scores in factor analysis? To reduce the number of factors To calculate the eigenvalues of factors To understand how objects score on the factors To determine the factor loadings 15 / 24 In factor analysis, what does the procedure primarily analyze? The regression coefficients The covariance matrix The mean of the data The correlation matrix 16 / 24 When is a correlation matrix considered suitable for factor analysis according to the Bartlett test of sphericity? When the variables in the sample are uncorrelated When the correlation matrix is equal to the inversed covariance matrix When the degrees of freedom are low When the correlation matrix is not an identity matrix 17 / 24 What does the communality of a variable in factor analysis measure? The uniqueness of the variable The proportion of variance in the variable explained by the factors The sum of the squared factor loadings for the variable The eigenvalue of the variable 18 / 24 In a factor analysis, what do the factor scores represent? Values per person on the latent factors Original variables Number of factors extracted Strength of correlations 19 / 24 What is the primary assumption about highly correlated variables in factor analysis? They are not suitable for analysis. They have no correlation. They should be reduced to a single variable. They are the result of common causes (factors). 20 / 24 What is the H0 of the Bartlett test of sphericity? The variables in the population are uncorrelated. The variables in the sample are correlated. The variables in the sample are uncorrelated. The variables in the population are correlated. 21 / 24 What is the difference between orthogonal and oblique rotation methods? There is no difference. Orthogonal rotation methods assume uncorrelated factors, while oblique methods allow for correlation between factors. Oblique rotation methods assume uncorrelated factors, while orthogonal methods allow for correlation between factors. 22 / 24 What is the difference between communality and eigenvalue? Check 23 / 24 What does CFA refer to when it mentions "reflective measurement models"? Models that reflect hypothetical constructs via measurement variables. Models that reflect the data structure without assumptions. Models that involve exploratory data analysis. Models that are highly complex and difficult to interpret. 24 / 24 What is one of the main objectives of factor analysis? To increase the number of correlating variables To increase the variance-covariance matrix To reduce a large number of correlating variables to a fewer number of factors To decrease the number of factors Your score is 0% Restart quiz Learn more…MethodsServiceAbout us ContactFeedbackOrder data etc. GeneralImprintPrivacy notice
