No of treatment Degrees of freedom= No of groups(k)-1= 5-1= 4
Denomenator degrees of freedom for test statistic(dferror)= Total degrees of freedom- No of treatment Degrees of freedom(dfbetween)
= 13-4= 9
Total observations(n)= Total degrees of freedom+1= 13+1= 14
Value of Fobs= F.INV.RT(0.05,4,9)= 3.633089
Sum of Squares total (SST)= Variance * (n-1)= (2^2)*(14-1)= 52
Lets say SSA= x,
SSE= 52-x
F= MSA/MSE=
= 3.633089
Solving for x gives x= 32.11
Therefore SSA= 32.11
SSE= 52- SSA= 19.89
MSE= SSE/dfError = 19.89/9= 2.21
MSA= SSA/dfBetween = 32.11/4= 8.028
The final Anova table is as shown below

Within Groups | 19.88868 | 9 | 2.209853 | |||
Total | 52 | 13 |

Investigators working on commericially cultivating shrimp are interested in determining the best conditions in which for them to grow. They are interested in knowing what impact water temperature (either 25 C, 30 C) and the salinity level (10 %, 25 % and 40 %) have on the growth of shrimp. Three replicates were used for each of the 6 possible treatment combinations. Post-larval shrimp were placed in each of the 18 tanks and fed the same amount of food. After...
Samples of three different species of amphibian (frog, toad and salamander) were collected and dissected and the number of parasites found within each was counted and recorded.

A study was carried out to assess the effect of a new medication in reducing blood pressure. In the trial, 59 subjects were enrolled, of which 30 were randomly allocated to receive a new treatment, while 29 received a control medication. After 20 weeks in the study, each subject's blood pressure, , was measured, leading to the following summary statistics: 9.63, 9.79, 1.41. With and representing the mean blood pressures in the treatment and control groups respectively, it is desired...
