Is there a way to calculate standard deviation on a semantic differential scale - 1(very dissatisfied) to 10 (delighted) scale? I have 100 respondents rating an attribute on this scale. How to calculate sd?

Generally it is not advisable to take the standard deviation of ordinal data although it is often done in practise. Depending on your needs perhaps a frequency table might summarise your data sufficiently?
