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?

2The formula doesn't change just because the scale might be limited or discrete: it's always the same. Are you perhaps wondering whether the result might be meaningful? Or how to interpret it? – whuber Aug 14 '18 at 16:20

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?
