Computing an Analysis of Variance (ANOVA)

After you have built your own Excel spreadsheet based on watching the video tutorial "Computing An Analysis Of Variance (Anova): Excel Video Tutorial (1:09:39)," edit your spreadsheet to enter the following scores for Group 3 (making sure that you keep the original scores for groups 1 and 2):

Group	Posttest
3	75
3	70
3	60
3	50

Suggestion: Choose to "save as" and give the spreadsheet a new name to show that it is the "quiz" version. The reason is that you may want to use or review the original spreadsheet (with the original scores) at some point in the future.

Note: A period is used to denote a decimal point (some participants may be accustomed to using a comma instead, but using a comma will result in the answer being scored as incorrect).

Answer the following question based on these new scores.
