    Likert analysis of survey data

    You cannot use a t-test for yes/no questions. If you asked people how many hours they spent online, then you could use a t-test. A t-test is not appropriate or meaningful for yes/no questions.

    Likert analysis of survey data

    Scorecard logic for measuring performance of managers

    Then it sounds to me like you're describing is actually an efficiency rating -- yes? You could simply compare the average number of hours/days/weeks/etc. needed to complete each task successfully. If the tasks really are all equally difficult, then that would be an easy comparison that will make...

    Scorecard logic for measuring performance of managers

    I guess I don't understand the question. Why do you not simply report each one as having an 80% on-time completion rate? (I assume in your real data they have different completion rates.)
