Hi,
1. Your Questionnaire is actually a 3-point scale no matter what you call the anchore (1,2,3 or 1,5,10) and actually represent the degree of separation from 'No' to 'Yes'
Hence you can safely code all your response to either 1,2,3 or stick to your anchores of 1,5,10 it dose not matter.
2. You can put code such as R1, R2, R3...etc in colums of Excel and put code for sample in 1st row. and you will have raw data.
3. Ensure that there are no missing data in any of the Qs otherwise do not include that in your analysis.
4. Aggregated score (Av. of R1-R12) will give you a score for employee's perception about her/his roles and Responsibilities...similalry you get a score for all the other parameters.
5. you can group your data dept-wise, level-wise as per your org. norms and tinker n see if the mean values change.
6. you can represent your data through charts (no. who respond to 1, nos who respond to 5, & nos who reponsd to 10)
7. Do a self study on how to calculate mean difference - i.e. if the mean on R&R for Exec is 3 and mean on R&R for Sups is 3.5 then is there a 'signifincant' difference between the two. Other wise 3.5>3 does not give you any meaningful analysis if the mean diff. is not significant and they actually are at the same level of perception.
8. there are host of possibilities of treating your data - but I guess from your responses you are at present not equipped to deal with them...do study further on Research Methods if you want to embark into a journey of greater data crunching.
Best Luck
