Next, enter "MAD =" into Cell A3 and the formula "=AVEDEV(A1:J1) into cell B3. You should see "#DIV/0 in Cell B2 and "#NUM!" in cell B3. Now enter "1" into cell A1. What do you get for the mean and the MAD of the data set?Other question:You are part of a school team planning a charity dog wash. You want to use data from last year's dog wash to predict how long it will take to wash a dog this year.Last year's dog washing team kept track of how long it took to wash each dog.
