WebHowever, some authors report means and standard deviations for each item on the measure, but do not calculate the overall mean and standard deviation. For example, for a measure with a 1-5 Likert-type response scale, rather than reporting a mean depression score of 2.5, sd = .34, for the whole scale, they'll report: item 1 mean 2.4, sd=.41 ...
