Just use abs(x - y) . This'll return the net difference between the two as a positive value, regardless of which value is larger. Please share simpler or more pythonic approaches, if you have one.

How to Find the Difference between Two Numbers. To find the difference between two numbers, subtract the number with the smallest value from the number with the largest value. The product of this sum is the difference between the two numbers. Therefore the difference between 45 and 100 is 55.

To calculate the percentage decrease between two numbers, you'll use an identical calculation to the percentage increase. You subtract the second number from the first, then divide it by the first number. The only difference is that the first number will be smaller than the second number.

Find the difference (subtract) between the accepted value and the experimental value, then divide by the accepted value. To determine if a value is precise find the average of your data, then subtract each measurement from it. This gives you a table of deviations.

First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number then this is a percentage decrease.

Percent Deviation From a Known Standard To find this type of percent deviation, subtract the known value from the mean, divide the result by the known value and multiply by 100.

Percentage Difference Formula The percentage difference between two values is calculated by dividing the absolute value of the difference between two numbers by the average of those two numbers. Multiplying the result by 100 will yield the solution in percent, rather than decimal form.

Since this is a binomial, then you can use the formula σ2=npq. f. Once you have the variance, you just take the square root of the variance to find the standard deviation.

An easy way to remember how to calculate percentage change between two numbers is: Take ending value and divide it by the beginning value, then subtract 1. Divide A2 by A1 and subtract 1.
