Percent difference 1 3 1 85 100.

Physics percent difference. Percent difference calculator solving for percent difference given two measured or experimental values. Percent difference 70 27. When wanting to compare two values that are both determined by experimentation we don t have a correct or accepted value to which to compare so we simply look at how different the two values are as a percentage of their average value.

As stated the percentage difference is be calculated by dividing the absolute value of the change by the average of the values and multiplying by 100. Value 1 value 2. Now the equation is 10 7 7 100 3 7 100 42 9 percent.

Formula to calculate percentage difference. 2 difference. Percent difference equations formulas calculator math science physics chemistry biology.

Value 1 value 2. Difference formula left d right frac n 1 n 2 frac n 1 n 2 2 times 100. Because the initial value for the second part of the problem is 7 rather than 10 the same absolute difference of three minutes creates a larger percentage difference.

Note both measured values need to be positive.
