to calculate percentage error, all you need to know is the approximate and exact value and you'll be on your way. Steps 1 Know the formula for calculating percentage error. The formula for calculating percentage error is simple:[1]'[(|Exact

Value-Approximate Value|)/Exact Value] x 100 The approximate value is the estimated value, and the exact value is the real value. Once you find the absolute value of the difference between the approximate value and exact value, all you need to do is to divide it by the exact value and multiply the result by 100. 2 Subtract the real number from your number. This means that you should subtract the real value from the estimated value. calculate error percentage In this case, the real value is 10 and the estimated value is 9. Ex: 10 - 9 = 1 3 Divide the result by the real number. Simply divide -1, the result when 10 is subtracted from 9, by 10, the real value. Place the fraction in decimal form. Ex:-1/10 = -0.1 4 Find the absolute value of the result. The absolute value of a number is the value of the positive value of the number, whether it's positive or negative. The absolute value of a positive number is the number itself and the absolute value of a negative number is simply the value of the number without the negative sign, so the negative number becomes positive. Ex: |-0.1| = 0.1 5 Multiply the result by 100. Simply multiply the result, 0.1, by 100. This will convert the answer into percent form. Just add the percentage symbol to the answer and you're done. Ex: 0.1 x 100 = 10% Community Q&A Search Add New Question How do I calculate a percentage error when resistors are connected in a series? wikiHow Contributor Carry the 2 and get the square root of the previous answer.

the experimentwise error rate is: where αew is experimentwise error rate αpc is the per-comparison error rate, and c is the number of comparisons. For example, if 5 independent comparisons were each to be done at the .05 level, then the probability that at least one of them would result in a Type I error is: 1 - (1 - .05)5 = 0.226. If the comparisons are not independent then the experimentwise error rate is less than . Finally, regardless of whether the comparisons are independent, αew ≤ (c)(αpc) For this example, .226 < (5)(.05) = 0.25.
