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.

Finding Area under a Normal Curve. Areas can be found under a normal curve by using the 68-95-99.7 rule if the areas are bounded at places where an exact standard deviation occurs. Areas that are not bounded at specific standard deviation units can be found by using a calculator or a z-table. Problem 1

Finding the Area under any Normal Curve. Draw a normal curve and shade the desired area . Convert the values of X to Z-scores using Z = (X – μ) / σ. Draw a standard normal curve and shade the area desired. Find the area under the standard normal curve. This area is equal to the area under the normal curve drawn in Step 1

The normal curve is a probability distribution and the total area under the curve is 1. For a normal distribution, approximately 68 percent of the data fall within one standard deviation of the mean, approximately 95 percent of the data fall within two standard deviations of the mean, and approximately 99.7 percent of the data fall within three ...
