What shape does a normal distribution take?

Bell Curve
Triangle
Square
Ellipse

The correct answer is: Bell Curve

A normal distribution takes the shape of a bell curve. This is because it is symmetric around the mean, with the data points forming a symmetrical, bell-shaped curve when plotted on a graph. The highest point of the curve represents the mean, with the data tapering off equally in both directions. This shape is characteristic of a normal distribution and is important in statistics for understanding probability distributions. Regarding the other options: B. Triangle, C. Square, and D. Ellipse do not represent the shape of a normal distribution. In statistics, a triangle would typically represent a triangular distribution, a square could represent a uniform distribution, and an ellipse does not correspond to any common distribution shape like the bell curve of a normal distribution.
