The Likert Scale is a type of attitudinal rating scale which asks people to show the extent to which they agree or disagree with statements. There are five to seven possible response choices. The most common scale is 1 to 5. Often the scale will be 1=strongly disagree, 2=disagree, 3=not sure, 4=agree, and 5=strongly agree. The result is obtained by calculating the average (i.e. mean) of all the results added together. Likert scales are often used in questionnaires to measure attitudes.
