Times more negative [closed]

I am writing a paper and recieved a result of lets say 5. Literature says it should be 4. However, it is possible to recieve negative values. Which sentence is correct:

1. The result is 25% more positive than the given value.

2. The result is 0.25 times more positive than the given value

3. The result is 125% more positive than the given value.

4. The result is 1.25 times more positive than the given value.

Either of the first two sentences is grammatically and mathematically correct. However, the possibility of a negative value has no real bearing on the comparison of two positive numbers. You can simply say, "The result is 25% greater."

Your third and fourth statements are mathematically incorrect. A value of 5 is 125% or 1.25 of 4, but not 125% "more" (that would be 9).

Lastly, the "given" value would refer to the score that was you received (the 5), not the one from the literature. I would call the latter the "prescribed" value, perhaps, or the "correct" value if you wish to make a truth statement.

What I would say is this:

The given result is 25% greater than the prescribed value.
