The following represents partial results for a oneway ANOVA: Source d.f. Sums of Squares Mean Squares Ftest Between 2 300 Within Total 23 800 Given the above partially completed ANOVA table, what is the value of the Ftest to determine if there is a significant difference in population means?
A. 15.67 B. 6.3 C. .375 D. 2.67
Solution:
We are given
MS = SS/df
F = MS between/MS within
The calculation table is given as below:

300/2 = 150 
150/23.80952381 = 6.3

23 – 2 = 21 
800 – 300 = 500 
500/21 = 23.80952381

Which of the following statements about the oneway ANOVA are correct? (Select all that apply) The larger the variability within groups relative to the variability between groups, the larger the F test statistic tends to be. The results of the ANOVA F test does not tel us which groups are different or how different they are. An Fdistribution is symmetrical about 0 and extends indefinitely in both directions In a oneway ANOVA, if the null hypothesis is rejected, we conclude that the population means...

ANOVA A study is designed to examine whether there is a difference in mean daily calcium intake among three groups of adults with normal bone density (Norm), adults with osteopenia (OstPNia) (a low bone density which may lead to osteoporosis) and adults with osteoporosis (OstPSis). A total of twentyone adults at age 60 was recruited in the study (7 adults in each group). Each participant's daily calcium intake was measured based on reported food intake and supplements in milligrams. We...
