4. Consider how dynamic questions are scored.

How do you calculate the mean of a survey?

For example, if you have four respondents to a survey, who have given the following satisfaction values (from a range of -2 to +2). To calculate the mean, you sum the values and divide by the number of cases. If you are scoring “Don’t know” as 0, your mean would be (-1 + 1 + 2 + 2 + 0) / 5 or 4/5.

What is mean score in research?
