A normal distribution is often described by the shape of its curve as:
AJ-shaped
BRectangular
CBell-shaped
DU-shaped
Answer & Solution
Correct answer: C. Bell-shaped
1. The visual signature of a normal distribution is unmistakable.
2. Height data for a large sample, for example, is asked about in terms of whether the curves would look bell-shaped.
3. The curve rises to a single peak at the mean and falls away symmetrically on both sides.
4. A rectangular shape would be a uniform distribution instead.
