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)=20

and

5*1=5 the highest possible score for yes/no question.

I then add up both highest possible score = 25.

If I total the score received by my survey based on the above sample size, I get a score totaling 20. 20/25 = 80%. Can I build my questionnaire and calculations like this? I want to pull out a score to see how well we are doing based on the survey questions. I am not sure if this is called a rating or score. I also want to know if this is the proper way to calculate this statistically.

----

My main objective is to get one percentage/score for the entire questionnaire. I thought of accomplishing this in 2 ways. 1. Get the sum of earned score from both scales divide by total possible scores for both scales. 2. Get a percentage by using the above calculation for individual scales, which will give me two set of percentages and then take an average for those percentages.

I am not sure if this is a statistically sound solution.

Can you please explain how I should proceed.

Thank you so kindly,
