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. img Based on the SPSS output below,what could you conclude? img Based on the SPSS Output below,that relates to the analysis of the sensation-seeking questionnaire,what could you conclude? img
