A rule of thumb decides when a histogram is the right display. From what size of data set upward is it recommended?
AFrom 100 values or more
BFrom 500 values or more
CFrom 250 values or more
DFrom 50 values or more
Answer & Solution
Correct answer: A. From 100 values or more
1. A histogram groups values into classes, so it earns its place once a listing would be unreadable.
2. The stated rule of thumb sets that point at 100 values or more.
3. Smaller sets are better shown by a stemplot, which keeps every individual value visible.
