The theoreticalvalue (using physics formulas)is 0.64 seconds. To find the value of 13 compared to 52, divide 13 by 52 = 0.25 Now the percentage is 100 times that or 25 percent. so divide by the exact value and make it a percentage: 65/325 = 0.2 = 20% Percentage Error is all about comparing a guess or estimate to an exact value. The term "human error" should also be avoided in error analysis discussions because it is too general to be useful. internet

These are reproducible inaccuracies that are consistently in the same direction. Another example: 16-15=-1. -1/15=-.067. .067*100=6.7% error. 13 people found this useful Answered by The WikiAnswers Community Making the world better, one answer at a time.
