Exercise 1 Page 420

The first thing that should be done when finding the mean of a data set is counting the number of values.

41.5 pounds

Practice makes perfect

The mean of a data set is calculated by finding the sum of all values in the set and then dividing by the number of values in the set.

Dog Weights (pounds)
Sparky: 18
Spot: 9
Rover: 60
Newton: 89
Diego: 44
Ruby: 13
Mookie: 54
Fido: 45

We can see that in the given data set, there are 8 dogs. Let's calculate the mean weight for dogs!

Mean=Sum of values/Number of values

SubstituteValues

Substitute values

Mean=18+9+60+89+44+13+54+45/8

Add terms

Mean=332/8

Calculate quotient

Mean=41.5

The mean of this data set is 41.5 pounds.
