Multiple Choice

A

A variable that shares none of its variance with any other variable would have a communality of:
Free
Multiple Choice

B

Marvin Zuckerman's work on dimensions of sensation seeking reveals four dimensions to this trait: (1)thrill and adventure seeking susceptibility to boredom (e.g.,being easily bored by predictable experiences and people).These dimensions are theoretically independent.Using the SPSS output below,do you think that the factor structure of the questionnaire supports Zuckerman's theory?

D

What does the following output from a factor analysis tell us?
Multiple Choice
Which of the following is true of factor scores?
Multiple Choice
An examiner of trainee chefs wanted to look at the underlying constructs of their 12 core culinary skills assessments.They ran a factor analysis with varimax rotation on the scores of the 12 assessments.Looking at the rotated factor matrix from their output below,which factor is the most likely to be labelled 'creativity'?
Multiple Choice
Based on this scree plot,how many factors should be extracted?
Multiple Choice
Marvin Zuckerman's work on dimensions of sensation seeking reveals four dimensions to this trait: (1)thrill and adventure seeking susceptibility to boredom (e.g.,being easily bored by predictable experiences and people).These dimensions are theoretically independent.A researcher was interested in designing a new questionnaire to measure sensation seeking.A 16-item questionnaire using a 5-point Likert scale (1 = strongly disagree,2 = disagree,3 = neither,4 = agree,5 = strongly agree)was devised and given to 750 people. Based on the SPSS output below,what could you conclude? Based on the SPSS Output below,that relates to the analysis of the sensation-seeking questionnaire,what could you conclude?
Multiple Choice
Based on the following output,which item on this questionnaire would most improve the reliability of the questionnaire if it were removed?
Multiple Choice
A reliability analysis was run on items from a questionnaire and gave rise to a Cronbach's alpha of α = -.8.What is the most likely explanation?
Multiple Choice
An examiner of trainee chefs wanted to look at the underlying constructs of their 12 core culinary skills assessments.They ran a factor analysis with varimax rotation on the scores of the 12 assessments.Looking at the rotated factor matrix from their output below,what would be a good label for factor 2?
Multiple Choice
Which of the following regarding the determinant of the R-matrix,denoted |R|,is false?
Multiple Choice
Which of the following sentences regarding the similarities of factor analysis and PCA is false?
Multiple Choice
Based on the scree plot below,how many factors should be extracted?
Multiple Choice
An examiner of trainee chefs wanted to look at the underlying constructs of their 12 core culinary skills assessments.They ran a factor analysis with varimax rotation on the scores of the 12 assessments.Looking at the rotated factor matrix from their output below,which factor is the most likely to be labelled 'preparation of fruit and vegetables'?
Multiple Choice
An examiner of trainee chefs wanted to look at the underlying constructs of their 12 core culinary skills assessments.They ran a factor analysis with varimax rotation on the scores of the 12 assessments.Looking at the rotated factor matrix from their output below,how many variables load onto factor 1?
Multiple Choice
A variable that has no unique variance (or random variance)would have a communality of:
Multiple Choice
A scree plot in factor analysis is a plot of:
