I am reviewing project OUTCOME for my library system and had a general question about the analysis I am seeing. There is debate in the research whether considering a Likert scale (i.e. Strongly Disagree to Strongly Agree) as continuous data is appropriate and valid. I tend to agree that Likert scales are not continuous and should be considered ordinal data. This would preclude the use of averages as a valid descriptive statistic which seems to be the majority of the analysis I am finding. This also brings additional ambiguity around the appropriate value to assign to the neutral response options (i.e. Neither Agree nor Disagree).
I would like to better understand project OUTCOME’s thoughts on these topics.
