Likert Scale Definition
The Likert scale is a five-point survey scale that gauges the attitude and interest any responding party may have towards any given subject matter. It’s useful for knowing what people are thinking. Scale ranges can measure: 5 – strongly agree, to 1 – strongly disagree. Mean score of 3 serves as the line between agreement and disagreement. Scores more than 3 are to agree very much, and scores less than 3 – to disagree very strong. Also, endless possibility of playing around with numbers and time.
Such a scale is used by giving a number to each available answer option on your 5 point scale. Than after, for each person taking survey math, the answer given to the respective number. So the number of responses for each option must be multiplied by the value. For example, if it’s ‘Strongly Agree’ and 10 people have chosen that option, then it’s 10*5. You do this for each answer that is there and find their sums. You would then find the total number of responses you have got and voila. To derive the average (median score), just simply divide this total by the number of people surveyed.
