You can code the answers to each question into numbers and then add up the numbers to get an overall attitude score for each participant. If the questions all measure a single trait or attitude when combined, they can also be grouped together and analyzed as a Likert scale. Likert-type questions can be individually analyzed for deeper insights into specific attributes. You can use descriptive statistics to summarize the data you collected in simple numerical or visual form. Overall Likert-scale data is often treated as interval because it is a composite score made from adding answers to 4 or more questions. For example, non-Likert rating scales from 1 to 10 can assume that the difference between 2 and 4 is the same as the difference between 5 and 7. Interval scales also have a clear order, but the difference between each point is evenly spaced. In ordinal scales, each item has a rank that is higher or lower than others, but the exact differences between the items aren’t evenly spaced or clearly defined.įor example, you can’t be sure that the difference between “very poor” and “poor” is the same as the difference between “good” and “excellent”. data from the overall Likert scale are treated as interval level.

Each question may measure a separate component of that overall topic.įor example, if you want to assess attitudes towards environmentally-friendly behaviors, you can design a Likert scale with a variety of questions that measure different aspects of this topic.
