Marvin Zuckerman’s work on dimensions of sensation seeking reveals four dimensions to this trait: (1) thrill and adventure-seeking (e. g., engaging in risky sports and activities); (2) experience seeking (e. g., traveling to exotic locations, experimenting with drugs, listening to exciting music); (3) disinhibition (e. g., going to wild parties, engaging in sexual activity with strangers); and (4) 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. a) The analysis has been conducted on an adequately sized sample. b) There is singularity in the data. c) The analysis has not been conducted on an adequately sized sample. d) It’s unclear whether the sample size is adequate but there is significant multicollinearity in the data.
