Why is it not necessary to use the ABS function in Excel when calculating Root Mean Squared Error?
Group of answer choices
Because both negative and positive numbers, when squared, are positive.
Because squaring of the individual errors means that the negatives no longer exactly cancel the positives.
Because the final calculation uses SQRT which cannot be applied to a negative number.
