My survey is based on observations and interviews. The observation questions are yes/no type questions and interview questions are 4 points.
1 = never, 2 = sometimes, 3 = usually, and 4 = always.
Yes = 1, No = 0.
If I add up all these with highest possible score and divide it by the total score received, I can then retrieve a total score for the survey.
For example, Let's say I have 5 responses for the likert and 5 for the yes/no. 5*4(with 4 being the highest possible score you can get on the likert)=20 and 5*1 (the highest possible score for yes/no question) = 5. I then add up both highest possible score = 25. If I get a combined score of 20 do I divide it by the possible score. 20/25 = 80%. Can I build my questionnaire and calculations like this?
My main objective is to get one percentage / score for the entire questionnaire. I thought of accomplishing this in 2 ways:
- Get the sum of earned score from both scales divide by total possible scores for both scales.
- Get a percentage by using the above calculation for individual scales, which will give me two sets of percentages and then take an average for those percentages.
I am not sure which way I should go with or if this even makes sense doing it this way.
