A mathematics department has been experimenting with four different delivery methods for content in their Algebra courses. One method is the traditional lecture (method I), the second is a hybrid format with half the class time online and the other half face-to-face (method II), the third is online (method II), and the fourth is a model from which students obtain their lectures and do their work in a lab with an instructor available for assistance (method IV). To assess the effectiveness of the four methods, students in each approach are given a final exam with the results shown in the accompanying table. Do the data suggest that any method has a different mean score from the others?
