What is the Normal Curve?

Back

The Normal Curve, also known as the Gaussian distribution, is a bell-shaped curve that represents the distribution of a set of data where most values cluster around a central peak and probabilities for values further away from the mean taper off equally in both directions.

What does it mean for a distribution to be symmetrical?

Back

A symmetrical distribution means that the left side of the curve is a mirror image of the right side, indicating that data is evenly distributed around the mean.

What is a characteristic of a Normal Distribution?

Back

A Normal Distribution is bell-shaped, symmetrical, and continuous.

Front

What is NOT a characteristic of Normal Distribution?

Back

Randomness is NOT a characteristic of Normal Distribution; it is structured and predictable.
