The normal frequency distribution curve or “bell” curve has now become a familiar way of displaying data. Unfortunately, there still exists a large gap in communication between the statistical engineer (Six Sigma Black Belt) and others mainly because of the technical jargon and the calculations involving formulas and tables.

The Normal Curve Percentages table below lists many more (330). Since the heights of the columns (bars) in a bar chart represent numbers (frequencies) of data values, and the widths of the bars are uniform, the areas of the bars therefore represent proportions (percentages) of the total population of data values that fall within certain ranges.

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.

A typical curve of the normal distribution is shown in the figure below. (A normal curve is sometimes called a “bell-shaped” curve.) Normal curves have certain defining characteristics. The most frequent values are found in the middle of the distribution, and taper …
