Extracting the factors Determining the factor scores Interpreting the factors Evaluating the suitability of the data 2 / 24 What is the primary assumption about highly correlated variables in factor analysis? They should be reduced to a single variable. They are the result of common causes (factors). They have no correlation. They are not suitable for analysis. 3 / 24 In factor analysis, what do factor loadings (ajq) represent? The variance of the observed variables The correlation between an observed variable and the extracted factor The sum of the squared factor loadings The number of observations (cases) 4 / 24 What is the H0 of the Bartlett test of sphericity? The variables in the sample are correlated. The variables in the population are correlated. The variables in the population are uncorrelated. The variables in the sample are uncorrelated. 5 / 24 What is the primary purpose of determining factor scores in factor analysis? To determine the factor loadings To reduce the number of factors To understand how objects score on the factors To calculate the eigenvalues of factors 6 / 24 How is the suitability of data for factor analysis typically evaluated? By calculating the correlation matrix By conducting a regression analysis By assessing inter-item reliability By examining means and standard deviations 7 / 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. 8 / 24 When is a correlation matrix considered suitable for factor analysis according to the Bartlett test of sphericity? When the correlation matrix is not an identity matrix When the degrees of freedom are low When the correlation matrix is equal to the inversed covariance matrix When the variables in the sample are uncorrelated 9 / 24 In a factor analysis, what do the factor scores represent? Original variables Strength of correlations Values per person on the latent factors Number of factors extracted 10 / 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 calculating the mean of the high-loading variables for each factor By using regression analysis on factor loadings By multiplying factor loadings by the number of variables 11 / 24 What does the communality of a variable in factor analysis measure? The sum of the squared factor loadings for the variable The eigenvalue of the variable The uniqueness of the variable The proportion of variance in the variable explained by the factors 12 / 24 In factor analysis, what does the procedure primarily analyze? The regression coefficients The correlation matrix The covariance matrix The mean of the data 13 / 24 What is the difference between orthogonal and oblique rotation methods? 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. There is no difference. 14 / 24 What statement(s) related to the KMO and MSA criterion are correct? KMO assesses the suitability of the correlation matrix. There is no difference between the two criteria. Both criteria measure the same. MSA assesses the suitability of a single variable. 15 / 24 What is the difference between communality and eigenvalue? Check 16 / 24 What does CFA refer to when it mentions "reflective measurement models"? Models that involve exploratory data analysis. Models that reflect hypothetical constructs via measurement variables. Models that reflect the data structure without assumptions. Models that are highly complex and difficult to interpret. 17 / 24 What is one of the main objectives of factor analysis? To reduce a large number of correlating variables to a fewer number of factors To decrease the number of factors To increase the variance-covariance matrix To increase the number of correlating variables 18 / 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 an average rating on the factor. An object is rated below average on the factor. An object has the highest rating on the factor. 19 / 24 What does the fundamental theorem of factor analysis state? It calculates the variance of factors It relates observed data to unobserved factors. It explains how to standardize data. It defines the correlation matrix. 20 / 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 1: Checking data suitability Step 4: Assessing factor scores 21 / 24 What is the primary objective of factor analysis compared to principal component analysis (PCA)? To reduce the dimensionality of data To uncover the common causes (factors) of observed variables and their correlations To maximize the explained variance by the extracted factors To eliminate unique variance in observed variables 22 / 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. 23 / 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 24 / 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.
