Consider an experiment with four groups, with eight values in each. For the ANOVA summary table below, fill in all the missing results:
Below, fill in all the missing results:
SOURCE DEGREES OF FREEDOOM SUM OF SQUARES MEAN OF SQUARE( variance) F
among groups c-1 = ? SSA = ? MSA=80 F stat=?
within groups n-c=? SSW=560 MSW=?
total n-1=? SST=?
11.6 You are working with the same experiment of table above.
a) at the 0.05 level of significance, state the decision rule for testing the null hypothesis that all
four groups have equal population means.
b) What is your statistical decision?
c) At the 0.05 level of significance, what is the upper-tail critical value from the Studentized range distribution?
d) To perform the Tukey- Kramer procedure, what is the critical range?
Step by step method for computing test statistic for One way ANOVA is given in the answer.
