How to Compute a Mean

After you have built your own Excel spreadsheet based on watching the video tutorial "Computing The Mean Of A Set Of Student Scores," edit your spreadsheet to enter the following new bowling scores for Cindy and Don:

	Score 1	Score 2	Score 3
Cindy	161	152	145
Don	95	88	119

Note: Update the scores for Cindy and Don, but don't delete the scores for Anne and Bob from your spreadsheet. That is, your updated spreadsheet should contain bowling scores for ALL four of the bowlers. Also note that 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 questions based on these new scores.
