What are the properties of a normal distribution?
Understand the Problem
The question is asking about the characteristics and features that define a normal distribution in statistics. Key concepts include the shape of the distribution, empirical rules (like the 68-95-99.7 rule), mean, median, mode, standard deviation, and how it relates to the concept of probability.
Answer
Mean, median, and mode are equal, symmetric distribution, and bell-shaped curve.
The main properties of a normal distribution are: mean, median, and mode are equal, the distribution is symmetric about the mean, and it forms a bell-shaped curve.

More Information
A normal distribution, also known as a Gaussian distribution, is fundamental in statistics due to its properties. It is used in various fields, including social sciences and natural sciences, to represent real-valued random variables whose distributions are not known.
Tips
A common mistake is confusing the shape of a normal distribution with a skewed distribution. Remember that a normal distribution is always symmetric.
