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?

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'?

Answer:

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?
