Question

The following table represents a two-factor experiment, with each factor having two levels. The numbers in each cell are the mean performance scores of each group after the experimental treatment. Note that one mean value is not given. What value of the missing mean would result in no interaction effect of factor A & factor B?                                                             B1             B2

A1	50	25
A2	35	?

• A. 5

• B. 10

• C. 15

• D. 20

• E. 25

Answer 1

sol Given that The felloosing table seporesents a tootector experiment BiBa A 50 Ag 35 Here we need to find out the missing mean would result in no-interaction between A and B. → Here while calculating the ditterences of mean for factor A A and lactor B are should have the same value. while choosing missing value so we have to choose the opproximate mean value. Consider the value os 50. we get Bi B9 average A Ag 49.5 average 42.5 37.5 50 25 37.5 35 50 Difference - 37.5 + 42.5 5 so, the difference of means for factor A and B are same, for so.
