How is η2 calculated for between-subjects ANOVA?

A researcher would like to evaluate the effect of three new reading program for second-grade students. For the school year, 1/4 of the second graders used program A, 1/4 used program B, 1/4 used Program C, and 1/4 used the current reading program. The researcher plans to use data from this study to test whether the new program has had a significant effect on reading scores. Which of the following hypothesis tests would be appropriate?

The values in the following matrix are treatment means from a two-factor study. One of the means is missing. What value for the missing mean would most likely result in main effect for factor A but not factor B?     B1 B2 A1 14 13 A2 6 ?

The values in the following matrix are treatment means from a two-factor study. One of the means is missing. What value for the missing mean would most likely result in no main effect for factor A?     B1 B2 A1 9 5 A2 7 ?

A sample of n = 100 scores is selected from a population with M = 80 with s = 20.  On average, how much error is expected between the sample mean and the population mean?
