 Question 12

Suppose a demographer states that these two samples are pretty much the same, so it doesn’t matter which one we use to represent Hayward. She would be what normal people call "hella wrong."

Keep in mind that a greater variety of scores, a mean that doesn't lean too young or too old, and a greater sample size are usually signs of better representativeness.

Which sample should she use if she wants to represent the diversity of Hayward?
