Answer:

Normal distribution is a Continuous distribution.

Step-by-step explanation:

Normal Distribution:

The following information is true about normal distribution.

  • ​Theoretically, the​ mean, median, and mode are the same.
  • Its parameters are the​ mean, mu​, and standard​ deviation, sigma.
  • About two thirds of the observations fall within plus or minus 1 standard deviation from the mean.

But normal distribution is not a discrete distribution. It is a continuous distribution.

  • The normal distribution is a continuous probability distribution. This has several implications for probability.
  • The probability that a normal random variable X equals any particular value is 0.
