Question

Quizplus · Accepted Answer

The symmetrical bell-shaped distribution that describes the expected probability distribution of many chance occurrences is called the normal distribution. This is a well-known concept in statistics and is used to model a wide range of natural phenomena. The other options, standardised normal distribution, sampling distribution, and randomised distribution, are related concepts but do not specifically describe the bell-shaped curve.
