How to calculate percent difference between two numbers?
Percent difference is similar to another term known as percent error. The only difference between the two is that percent error measures the difference between an accepted value and an observed value, whereas, neither of the values used in the calculation of percent difference are the accepted ones. Both are experimental values describing the same characteristic or property. Given below is the formula for calculating percent difference between two observed values. Percent Difference = { ( |Value 1 – Value 2| ) / [ (Value 1+ Value 2) / 2 ] } X 100 Here, as none of the values are actual or accepted, the absolute difference between them has to be divided by the average value that is obtained by taking the mean of the two given values. It is very important that both the values that are to be compared should have the same units. Another important thing to remember, is that the difference calculated (|Value 1 – Value 2|), is the absolute difference, that is you have to take the modulus of th
