Question

which of the following distributions would have the least variation? a. weights of all children who have a pet cat b. weights of all pet dogs c. weights of all pets d. weights of all pet cats

Explanation:

Variation in a distribution is related to the spread of data. A more homogeneous group will have less variation. Pet cats are a more specific and homogeneous group compared to all children with a pet cat (children vary in age, size etc.), all pet dogs (different breeds vary in size), and all pets (a very diverse group including cats, dogs, birds, fish etc.).

Answer:

D. Weights of all pet cats
