One thing that can be very confusing is why the Likert scales appear to be ordinal but are almost always used as interval levels of measurement. As Wikipedia describes it: “While a Likert scale is indeed ordinal, if well presented it may nevertheless approximate an interval-level measurement” (“Likert Scale,” 2021, Scoring and Analysis section, para. 5 ).
