I'm writing a scientific paper, and I want to know what is the best adjective to use with the word "accuracy" in the following sentence:

"... the method A has ____ accuracy when compared to method B".

Should I use a) better, b) higher, c) greater, or d) another adjective?

Here I am using the word accuracy to refer the closeness as a technical term, with the meaning of "the degree to which the result of a measurement is close to the correct value."

EDIT: Adding more context.

I am writing a statistical paper. In this paper, I am comparing two estimation methods in a simulation study. In that simulation study, I have a true value of an parameter, and I am comparing that value with the value obtained (called the estimate) with each method.In this context, accuracy refers to how close the estimate is to the actual value.

    method A is more accurate than method B. Use the adjective, not the noun, in English. Spanish and Portuguese and French would use the noun: The accuracy of A is greater than B. You are probably being influenced by one of those.

While "better," "greater," and "higher" all work here, there is a much simpler way of saying this:

method A is more accurate than method B.

(This is correct even if you are using the word "accuracy" in the technical, scientific sense.)

The adjectives all have slightly different meanings. Without more context it is impossible to say which is best.
better implies that the method A was possibly using better equipment or technique or it was somehow less prone to inaccuracies and external influences.
higher implies that the result had less error tolerance, for example +/-1% instead of +/-5%
greater is similar to higher

  • Actually, it sounds like the poster is making the usual scientific distinction between accuracy (closeness to the correct value) and precision (degree of uncertainty or repeatability), so no adjective applied to accuracy would properly say anything about error tolerance. If you wanted to imply less error tolerance, you would say higher precision. Mar 15, 2023 at 14:41
