The students in Class A and Class B were asked how many pets they each have. The dot plots below show the results.

Students in Class A
A dot plot titled Students in Class A. A number line going from 0 to 5 labeled Number of pets. There are 5 dots above 0, 5 above 1, 4 above 2, 1 above 3, and 0 above 4 and 5.

Students in Class B
A dot plot titled Students in Class B. A number line going from 0 to 5 labeled Number of pets. There is 1 dot above 0, 2 above 1, 2 above 2, 4 above 3, 3 above 4, 3 above 5.

What is the difference between the ranges in the dot plots?
0
2
3
4

1 answer

To find the range of each class's dot plot, we need to determine the maximum and minimum values for the number of pets.

Class A:

  • Minimum value: 0 (the lowest number of pets)
  • Maximum value: 3 (the highest number of pets)
  • Range for Class A = Maximum - Minimum = 3 - 0 = 3

Class B:

  • Minimum value: 0 (the lowest number of pets)
  • Maximum value: 5 (the highest number of pets)
  • Range for Class B = Maximum - Minimum = 5 - 0 = 5

Now, to find the difference between the ranges of Class A and Class B:

  • Difference = Range of Class B - Range of Class A = 5 - 3 = 2

So, the answer is 2.
