What is Meant by Normal Distribution?

Normal distribution is a probability distribution in which most data values tend to cluster around the mean. It is also known as the “Gaussian Distribution”. The bell-shaped curve is another name for the normal distribution curve. Although all normal distributions are symmetrical, not all symmetrical distributions are normal distributions.

Normal Distribution Curve

The distribution is said to be normal if it meets the following criteria:

  • All the Mean, Median & Mode are equal
  • It is symmetric about the centre.
  • Exactly 50% of data is greater then mean and 50% are lesser.

FAQ

What is a normal distribution in statistics?

Normal distribution is basically 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.

What are the characteristics of a normal distribution?

Normal distributions are symmetric, unimodal, and asymptotic, and the mean, median, and mode are all equal. A normal distribution is perfectly symmetrical around its center.
