 Solution

TODO: neither the significant effects nor their numerical effect sizes can be determined. Inspect the output's significance results and the definition of its reported effect size. If it supplies partial eta squared, that quantity is $S{S}_{\text{effect}}/(S{S}_{\text{effect}}+S{S}_{\text{error for effect}})$; it is not automatically ordinary eta squared or a fraction of all observed variation. Repeated-measures conventions and the selected error term matter. Report the actual metric and preferably an uncertainty interval; do not manufacture an effect size from the number of participants.
