Although I appreciated the thoroughness to which the descriptive statistical was explained, I wasn’t convinced the mean was the best indicator for the data, considering that evaluation scores were collected on a 5-point scale and not a continuous linear one.

Figures 1 and 4 can be removed, as the assumption of normality no longer applies (also on P15, L399-400), or replaced with boxplots.
