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.data from individual Likert-type questions are treated as ordinal level.Your data can be divided into these two different types because they are associated with separate analysis procedures. I try to buy organic products whenever possible.īanning single use water bottles is pointless for reducing environmental damage.īefore you analyze data from Likert-type questions and Likert scales, it’s important to consider what type you’re dealing with.

If all your questions only ask about things in socially desirable ways, your participants may be biased towards agreeing with all of them to show themselves in a positive light.Įnvironmental damage caused by single use water bottles is a serious problem. Use both positive and negative frames in your questions. When deciding how to phrase questions and statements, it’s important to ensure that they are easily understood and do not bias your respondents in one way or another. Using a mix of both can keep your participants engaged and attentive during your survey. Phrasing as questions vs statementsīoth statements and questions are often used in Likert scales. 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.
