What is a normal distribution?

What is a normal distribution?

A normal distribution is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Can you explain the significance of the mean and standard deviation in a normal distribution?

Sure! The mean is the average of the data set, and the standard deviation measures the spread of the data around the mean. In a normal distribution, about 68% of the data falls within one standard deviation of the mean.

What does the bell curve represent?

The bell curve represents the shape of the normal distribution, where most of the observations cluster around the central peak and probabilities for values further away from the mean taper off symmetrically.

How is normal distribution used in real life?

Normal distribution is used in various fields such as psychology, finance, and natural sciences to model real-world phenomena, like test scores or heights.
