‘Precision’ vs ‘Accuracy’: What’s the difference? Sometimes, words overlap in meaning, yet we rely upon them because of their distinctions. This article will help you become more precise and accurate with your language use while learning the difference between ‘Precision’ vs ‘Accuracy’.
Are you in a rush? Here’s a preview of what’s to come:
- ‘Precision’ is a term that deals with the exactness of something in relation to others
- ‘Accuracy’ is a term that deals with the correctness of something in relation to a goal
What’s the Difference Between ‘Precision’ vs ‘Accuracy’?
One of the main reasons these terms are often confused is because they appear in each other's definitions. That is to say that ‘Precision’ can sometimes be defined as being accurate while ‘Accuracy’ can be defined as how precise we are. But does that mean they are the same thing? No, they’re not.
The first degree of separation between the two lies in their definitions, showing us there are better terms to describe their meanings.
- ‘Precision’ is defined by exactness, or how close items are relative to each other.
- ‘Accuracy’ is better described by correctness, or how close items are to a target.
It is important to note that the “items” in question can be all sorts of things, varying from numbers or data on a graph to shots on a target. In fact, let’s use the target example to visualize the key differences between ‘precision’ vs and accuracy.’
Visualizing ‘Precision’ vs ‘Accuracy’
Say there are four people shooting at a round target, with the goal clearly being to hit the bullseye in the middle as many times as possible. Let’s take a look at each person’s outcome to see how they demonstrate ‘precision’ vs ‘accuracy.’
Shooter A has shots all over the target, none of which are close to the bullseye and are all in random spots across the board.
- Shooter A has no ‘precision’ or ‘accuracy.’
Meanwhile, Shooter B seemed to have better aim and had a bunch of shots clustered together, but they were all skewed right and above the bullseye.
- This means that Shooter B had decent ‘precision’ because the shots were close to each other but bad ‘accuracy’ because they missed the bullseye.
Shooter C managed to land all of their shots in the ring directly outside the bullseye, but they’re spread out like sprinkles on a donut.
- So, Shooter C had good ‘accuracy’ because they were close to the center but needed better ‘precision.’
Finally, Shooter D hit the bullseye dead on every time and created a hole in the target right in the center. Their ‘precision’ and ‘accuracy’ were on point.
Hopefully, visualizing the difference between our new terms made them easier to understand compared to each other. But let’s make sure you know everything about ‘precision’ vs ‘accuracy’ individually as well.
