Question

An illustration shows two sets of dot plots. One is titled Weight in Pounds, Cats and the other is Weight in Pounds, Small Dogs. The plots are shown as an abacus-like representation with dots in a vertical row over each number on a number line. For Cats, a number line with arrows on both ends ranges from 9 to 13 in increments of 1. There is 1 dot above 9, 2 dots above 10, 4 dots above 11, 2 dots above 12, and one dot above 13. For Small Dogs, a number line with arrows on both ends ranges from 8 to 15 in increments of 1. There is 1 dot above 8, 2 dots above 9, 4 dots above 10, 2 dots above 11, 2 dots above 12, 2 dots above 13, 1 dot above 14, and 1 dot above 15.

The dot plots show the weights of randomly selected cats and small dogs in different households. What is the difference between the modal weights of cats and small dogs?

Answer 1

The modal weight of cats is 11 pounds, as there are 4 dots above 11 on the dot plot. The modal weight of small dogs is also 11 pounds, as there are 4 dots above 10 on the dot plot. Therefore, the difference between the modal weights of cats and small dogs is 0 pounds.

Answer 2

ummm so how is the modal weight of dogs 11 if the four dots are on 10?
