# The normal curve is an example of what type of graph?

A) Bar graph

B) Smooth curve

C) Histogram

D) Frequency polygon

Normal Curve

A theoretical distribution of scores where the mean, median, and mode all share the same value and an equal percentage of scores fall on either side of the distribution. Also called a bell-shaped curve based on the visual form this type of distribution takes when graphed.

Smooth Curve

A type of curve in graphical representations that is continuously differentiable and does not have any sharp angles or breaks.

Frequency Polygon

A graphical representation of the distribution of numerical data, where a continuous line connects points representing the frequency of scores within intervals.

Final Answer :

B

Explanation :

The normal curve is a smooth curve that represents the distribution of a set of data that is symmetrical and bell-shaped, with the highest frequency occurring at the mean and decreasing as the values move away from the mean. It is also known as the Gaussian distribution or bell curve. Therefore, B is the best choice as it describes the normal curve accurately.
