The graph of a normal distribution has which overall shape?
AA single central hump
BA flat straight line
CA deep central dip
DA rising staircase
Answer & Solution
Correct answer: A. A single central hump
1. Most values in a normal distribution cluster near the middle.
2. Fewer values appear as you move out towards either tail.
3. That pattern draws a bell, a single hump in the middle with two falling tails.
