This dot plot shows the weights of backpacks of 50 sixth-graders.

Chanel thinks that 3 kilograms is a typical backpack weight because it has the largest portion of the data.

Tyrell thinks that 3 kilograms is too low to describe a typical weight because half of the dots are for backpacks that are heavier than 3 kilograms, so he would use a larger number.

Who do you agree with?
