Likert Scale
A rating format asking respondents to state their level of agreement with statements, typically on a five- or seven-point scale.
A Likert scale presents a statement and asks respondents to choose a position on an ordered range, most commonly from strongly disagree to strongly agree across five or seven points. Strictly, the term refers to a set of such items summed or averaged to measure an underlying attitude, while a single item is a Likert-type item. The responses are ordinal, meaning the categories are ordered but the gaps between them are not guaranteed to be equal, which shapes which statistical tests are appropriate.
In a thesis, Likert scales are among the most common measurement tools, and examiners know their pitfalls. Justify the number of points, keep labels consistent, and say whether you analyzed single items or composite scores. If you treat summed scales as interval data for parametric tests, state that choice explicitly, and consider reporting reliability with Cronbach's alpha.
