The observed F value (Fobs) for a factor or interaction in an ANOVA is calculated by dividing the mean square (MS) of that factor or interaction by the mean square error (MSError). For factor A, Fobs = MSA / MSError = 4.00 / 2.00 = 2.00. For factor B, Fobs = MSB / MSError = 10.00 / 2.00 = 5.00. For the interaction of factors A and B, Fobs = MSA×B / MSError = 6.00 / 2.00 = 3.00.
