In оrder tо meаsure the degree оf аrousаl generated by viewing emotional advertisements, I exposed study participants to a website that featured five emotional ads. After exposure, I asked them to fill out a questionnaire, which had 10 items pertaining to self-reported arousal level. All these questions were anchored on a 1-5 scale, with "1" representing "highly aroused" and "5" representing "not at all aroused." I then added up the responses to the 10 questions and constructed a variable called "Cumulative Arousal." a) Does the Cumulative Arousal variable wiggle? b) Operationally, what level of measurement does the Cumulative Arousal variable attain? (c) Scores on the Cumulative Arousal variable were highly negatively correlated with levels of skin conductance, which is an established measure of physiological arousal. What does this say about the validity of my Cumulative Arousal variable? Why?
