Each column represents one of the perception items. The firstone is the negative-positive scale, the second the dirty-clean scale, the third the useless-usefulscale, and last column is the dangerous-safe scale. The explanatory values of the measuredknowledge items vary between adj. R 2 = .18 and adj. R 2 = .26, which are all fairly low. This meansfor example that 24% of the variance of answers people give on the negative-positive scale areexplained by the knowledge items in the survey. The other 76% is explained by factors notmeasured in this part of the survey. For a summary of results, see report body text.70 | Understanding how individuals perceive carbon dioxide
