To calculate percentage error, you subtract the actual number from the estimated number to find the error. Then, you divide the error in absolute value by the actual number in absolute value. This gives you the error in a decimal format. From there, you can multiply by 100% to find the percentage error.

In the example, assume there are 20 pieces of data in all. Divide the non-overlapping data points by all the data points to calculate the percentage of non-overlapping data points. In the example, 10 divided by 20 equals 0.5. If you multiply this by 100, it will convert it into the percentage form of 50 percent.

Consider the normal distribution N(100, 10). To find the percentage of data below 105.3, that is P(x < 105.3), standartize first: P(x < 105.3) = P ( z < 105.3 − 100 10 ) = P(z < 0.53). Then find the proportion corresponding to 0.53 in Table A: look for the intersection of the row labeled 0.5 and the column labeled .

To calculate a percentage of a percentage, convert both percentages to fractions of 100, or to decimals, and multiply them. For example, 50% of 40% is: 50100 × 40100 = 0.50 × 0.40 = 0.20 = 20100 = 20%.

The mathematical formula for calculating percentage is as follows: (part / whole) * 100. To find a percent of a number, use this variant of the formula: (number * percent) / 100. Or move the comma in percentage by 2 characters to the left and perform only multiplication. For example, 10% of 100 is 0.1 * 100 = 10.
