It calculates the error rate as a running statistic, by dividing the total number of unequal pairs of data elements by the total number of input data elements from one source.Use this block to compute either symbol or bit error rate, because it does not consider the magnitude of the difference between

or real value. Then, convert the ratio to a percent. We can expresss the percent error with the following formula shown below: The amount of error is a subtraction between the measured value and the accepted value Keep in http://www.basic-mathematics.com/calculating-percent-error.html mind that when computing the amount of error, you are always looking for a positive https://en.wikipedia.org/wiki/Error_rate value. Therefore, always subtract the smaller value from the bigger. In other words, amount of error = bigger − smaller Percent error word problem #1 A student made a mistake when measuring the volume of a big container. He found the volume to be 65 liters. However, the real value for the volume is 50 liters. What is the percent error? Percent error rate error = (amount of error)/accepted value amount of error = 65 - 50 = 15 The accepted value is obviously the real value for the volume, which 50 So, percent error = 15/50 Just convert 15/50 to a percent. We can do this multiplying both the numerator and the denominator by 2 We get (15 × 2)/(50 × 2) = 30/100 = 30% Notice that in the problem above, if the true value was 65 and the error rate calculation measured value was 50, you will still do 65 − 50 to get the amount of error, so your answer is still positive as already stated However, be careful! The accepted value is 65, so your percent error is 15/65 = 0.2307 = 0.2307/1 = (0.2307 × 100)/(1 × 100) = 23.07/100 = 23.07% Percent error word problem #2 A man measured his height and found 6 feet. However, after he carefully measured his height a second time, he found his real height to be 5 feet. What is the percent error the man made the first time he measured his height? Percent error = (amount of error)/accepted value amount of error = 6 - 5 = 1 The accepted value is the man's real height or the value he found after he carefully measured his height, or 5 So, percent error = 1/5 Just convert 1/5 to a percent. We can do this multiplying both the numerator and the denominator by 20 We get (1 × 20)/(5 × 20) = 20/100 = 20% I hope what I explained above was enough to help you understand what to do when calculating percent error Any questions?
