Analysing a nominal and ordinal variable

Part 4: Reporting

If we combine all the reporting bits from the example, the full report for this variable, might have looked something like:

The teacher for the class was different at each location. Students were asked how motivational they found the teacher at each location. The results are shown in Figure 1.

Figure 1. Location vs Teacher motivation.

As can be seen Figure 1 the students in Diemen found the teacher more motivational than those in Haarlem and Rotterdam.

A Kruskal-Wallis test showed that Location had a significant relatively strong effect on how motivated students were by the teacher, χ²(2, N = 54) = 21.33, p < .001, Ε² = .40. A post-hoc test using Dunn's test with Bonferroni correction showed the significant differences between Diemen and Haarlem, p < .05, and between Diemen and Rotterdam, p < .001.

It appears that the teacher in Diemen motivated the students better than those in Rotterdam and Haarlem. During a focus session with the students from each location it became clear that this might have been because……..

Note the final paragraph explains the some-what technical results into more understandable English, something many readers would often appreciate.
