In calculating averages of the results, each possible answer is given a numerical value from 1 to 5, where 1 is the lowest answer option (never, not at all effective, not at all, etc.) and 5 is the highest answer option (always, very effective, very much, etc.). The average result is calculated finding the average from each question’s responses.
The average results are useful to gain a quick understanding of the results, especially for comparing different questions or groups. However, to gain a more in-depth understanding of your results, you should review individual bar graphs because the average does not show how diverse the question answers have been – if responses are all clumped to one side or very spread out.
To calculate the normalized weight for the answer responses we use the formula: (X-1)/(n-1)*4+1, where X is the answer option weight and n is the number of answer options.
