There are two types of simple normal distribution problems: 1) given an x-value to find an area, and 2) given an area to find an x-value. If the problem is to find an area, then: 1) draw a picture, 2) calculate the z-score, 3) use the table to look up the area.

The symmetrical histogram would have a bell shaped line. This is known as a normal distribution. Under the normal distribution curve we have 100% of an area under the curve, just like if you were to find the area of a square or a circle you would have 100%. 50% of the area lies to the left of the mean, and the other 50% lies to the right of the ...

Normal Curve. Although frequency distributions can be of any shape (unimodal, bimodal, peaked, flat, skewed, etc.), there is one pattern that occurs in such a wide variety of circumstances that it is regarded as the single most important type of data distribution in all of statistics.

The normal distribution curve is sometimes called the ‘bell curve’ or the ‘Gaussian curve’ after the mathematician Gauss, who played an important role in its development. Early on, the normal distribution was used to model and manage the errors received during astronomy investigations, though its applications are more wide ranging today.
