A faculty member wanted to investigate the effects of classroom modality on learning in a statistics course. She conducted an experiment where she randomly assigned 45 students to one of three classroom modality conditions: in-person, online synchronous, or online asynchronous. 15 students were assigned to each condition. She presented the same three lectures to each group of students: one each on binomial probability distributions, simple regression, and factorial ANOVA. Students attended each lecture and after each lecture took an examination that measured their mastery of the topic. Partial results from her analysis are presented in the table below. Complete the table and compute the appropriate F values. Indicating which effects are significant at p <.05. source sum of squares df ms f lecture class modality x subjects>
