Question

Project: Assess the impact of teaching style (F2F, Web, Mixed) on mean introductory sociology grades. Please determine if any of the groups differentiate themselves from the others using the .05 probability level.

F2F Web Mixed

Person 1 94 80 85

Person 2 78 74 83

Person 3 87 75 79

Person 4 90 76 80

Person 5 82 83 80

Please determine if the groups differ significantly and what that means.

Answer 1

Using Minitab, (Stat -> ANOVA -> One Way),we get the following output -

Here,

The value of F statistic F = 0.8

and P-value = 0.55

Since P-value > 0.05, so we fail to reject H₀ at 5% level of significance and we can conclude that the groups do not differ significantly among themselves.
