A Sports Coach Running a Junior Coaching Programme Was Interested

A sports coach running a junior coaching programme was interested in examining the differences in children's fitness performance scores across four different coaching regimes. She was particularly interested in whether the regime the child was in had a possible influence on the child's fitness performance score. She ran an ANOVA with the predictor variable 'coaching regime', which had four categories, 'Yellow group', 'Green group', 'Pink group' and 'Purple group'; the outcome variable was 'fitness performance score'. Her ANOVA had an F-statistic of 98.12 (p 0.02) . How would you interpret her findings?

A) There is a significant difference in children's fitness performance score by coaching regime.
B) There is no significant difference in children's fitness performance score by coaching regime.
C) There is insufficient information; the results of Post hoc tests are needed.
D) The results are ambiguous.
