The Likert Scale is the most commonly used scale in quantitative research.

The original version of the scale included 5 response categories, and each response category was assigned a value.

Usually, the most negative response is given a numerical value of 1, whilst the most positive response has a numerical value of 5.

Obviously you can work out that the point in the middle would have a numerical value of 3.

Response choices in a Likert Scale usually address:


Example of a Likert Scale:


This method of teaching you about quantitative research methodology is useful.

Likert Scale:

  •  strongly agree           5
  •  agree                        4
  •  uncertain                   3
  •  disagree                    2
  •  strongly disagree       1



However, do take note that the use of the 'uncertain' or a 'neutral' category is controversial because it allows the subject to avoid making a clear choice of positive or negative statements.

Consequently, sometimes only four or six options are given, and when this happens, it is known as a forced choice Likert Scale.
