An analysis of variance demonstrated the following results for course sense of
community, (2, 27) = 2.56, = .07. Students in online courses ( = 12.4, = F p M SD
2.26, = 10), blended courses ( = 13.62, = 5.56, = 10), and the residential n M SD n
courses ( = 14.65, = 7.56, = 10) were measured on their sense of community.M SD n
What can be concluded based on these results?
Selected
Answer:
The average sense of community did not significantly differ among the
online condition ( = 12.4, = 2.26, = 10), the blended condition M SD n
(M M = 13.62, SD = 5.56, n = 10), and the residential condition ( =
14.65, = 7.56, = 10).SD n
