Closeness to correctness.

If the true answer is 5, then an approximation of 4 is more accurate than an approximation of 1. It the true answer is orange then an answer of red is more accurate than one of blue.

If in determining a bacterial unknown, if the actual organism is *Salmonella* then a determination that instead it is *Proteus* (a fellow Gram-negative rod and enteric) is more accurate than a determination of *Staphylococcus* (a Gram-positive coccus) or, indeed, *Saccharomyces* (a eukaryote rather than a prokaryote).

Of course, answers of 5, orange, and *Salmonella* would be most accurate of all!
