Learning Objective 4 • Number of Items in a Scale • The four previous examples had four items (i.e., questions) each • Could a global measure (e.g., an overall evaluation) have provided the same insight? • What is your overall evaluation of Cover Girl mascara? • Number of Scale Positions • The Summated-Rating and Semantic-Differential examples had five scale positions each • Would six have been better? Seven? MR/Brown & Suter

Learning Objective 4 • Including a “Don’t Know” or “Not Applicable” Response Category • If you are unfamiliar with Cover Girl mascara and its attributes, would the opportunity to state that these questions do not apply be helpful? • Reverse Scaling • The Summated-Rating example had two positively worded and two negatively worded items • Positive: long-lasting, volume boosting • Negative: smudges, runs when wet MR/Brown & Suter
