To find the percentage difference between two images, you first need to quantify the differences between them, typically by comparing pixel values. One common method is to calculate the mean squared error (MSE) or the root mean squared error (RMSE) between the corresponding pixels of the images. Once you have the error value, you can express the percentage difference by dividing this error by the maximum possible value (e.g., the maximum pixel value) and multiplying by 100. This will give you a percentage that represents how much the two images differ from one another.

I assume you want to take the absolute value of a set of data, find the average and convert it to a percentage. For example, my data set is -1 -5 -3. The absolute values sum to 9, the average is 3 and presented as a percentage, it is 300%. I would put in my excel spreadsheet the numbers in a single column (let's call it a2, a3, a4) then in b2 cell, enter +abs(a2) and copy down. At the bottom of the absolute values, enter +average(b2:b4) or whatever your range is. You can use format cell option under edit to convert to %.
