Comments on Survey

One issue with the Library Survey is that it does not assign a description to each score. The Survey only gave a description of Low for a score of 1, and a description of High for a score of 7. The Survey should improve on this by providing descriptions for each score. An example given:

Score	Description
1	Not important at all / Not satisfied at all
2	Not important / Not satisfied
3	Slightly not important / Slightly unsatisfied
4	Neutral
5	Slightly important / Slightly satisfied
6	Important / Satisfied
7	Extremely Important / Extremely satisfied

By providing descriptions, survey respondents will have a better idea of what each score represents. However, for the purposes of analysing this survey, I will assume that the scores follow a score of 1 to 7.
