Two different vets report the weights of the dogs they checked in one day.

Weight of Dogs
Vet 1 6 12 20 25 27 32 70 70 70 81 99
Vet 2 5 8 13 17 22 36 36 50 80 90 110

Which statement is true?


The median weight was greater for Vet 1.
The mean weights were the same for both vets.
The range of the data is 12 greater for Vet 2.
There are more modes for Vet 2.

To find the median weight, list the weights for Vet-1 from smallest to largest (if there are an even number of weights, find the middle value between the middle two weights). Then do this for Vet-2 and compare your answers.

To find the mean weight, add all the weights for Vet-1 and divide by the number of weights for that vet. Do the same for Vet-2 and compare your answers.

To find the range, subtract the smallest number from the largest number for Vet-1. Do the same for Vet-2 and compare your answers.

The mode is the number used most often for each vet. If every number is used only once, there is no mode. There can be two modes, if two numbers are tied for greatest usage.
