Problem: What is a Likert scale? A Likert scale is a survey response scale that represents a range of answer options on a topic. It is a 5 or 7-point scale that ranges from one extreme attitude to another, such as "extremely likely" to "not at all likely." Typically, they include a moderate or neutral midpoint.
