What’s up everyone. I have a question in regards to some work I’m doing. I need to get the total accuracy.

Here is the problem:

I have -

Expected Number
Actual Number

The difference between the expected and actual number are both positive and negative variances

Currently I turned both positive and negative numbers to absolute values.

The formula I am using = 1 - (variance(Absolute)/expected number) * 100%

Is this the correct way to get the total accuracy?
