Analysis Of Variance (ANOVA)


Example: ANOVA Single Factor

You are the production manager of a large bottling company and you are evaluating 3 new machines to fill your bottles. You are very concerned with the speed at which the machines fill the bottles and want to make your selection based on the best (fastest) fill time.

You assign 15 similarly trained workers to the 3 machines, 5 per machine and conduct the fill time tests. The results of your experiment are recorded.

At a significance level of .05 determine if there is a difference in the average fill time of the 3 new machines.

It wishes to compare the distance used by 3 different brands of golf ball when hit by a driver and a 5 iron. 6 balls from each brand are chosen and hit with the USGA robot called the Iron Byron. The distances are recorded here.
