## How do you determine if a distribution is approximately normal?

A normal distribution is one in which the values are evenly distributed both above and below the mean. A population has a precisely normal distribution **if the mean, mode, and median are all equal**. For the population of 3,4,5,5,5,6,7, the mean, mode, and median are all 5.

## What is approximately normal?

A distribution is approximately Normal **when the Normal distribution can be used as an approximate distribution**. This is common when the number of samples or parts making up a distribution grows; for example, if you have 100 coin tosses the resulting Binomial distribution is, for most purposes, approximately Normal.

## What is approximately normal distribution?

Intelligence test scores follow an approximately normal distribution, meaning that most **people score near the middle of the distribution of scores**. … For example, on the IQ scale, about two-thirds of all scores fall between IQs of 85 and 115, and about 95% of scores fall between 70 and 130.

## What makes a histogram a normal distribution?

A common pattern is the bell-shaped curve known as the “normal distribution.” In a normal or “typical” distribution, **points are as likely to occur on one side of the average as on the other**. Note that other distributions look similar to the normal distribution.
