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. Therefore, for the purposes of analysing this survey, I will assume that the scores follow the table above.
