A) Yes,because the forty trials were identical and tested the same research question and therefore we can calculate an average effect size for 'Bouncy Phonics'
B) Yes,because the forty trials were identical and tested the same research question and therefore we can calculate an average significance for 'Bouncy Phonics.
C) No,because the forty trials were identical and tested the same research question we cannot calculate an average effect size for 'Bouncy Phonics.
D) No,because the forty trials were identical and tested the same research question we cannot calculate an average significance for 'Bouncy Phonics.
