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