What is precision in chemistry?

Regardless of how "correct" your answers are, precision is the proximity of your answers to one another.

Think of a large Bullseye target.

You are precise if all of your hits are close to one another even if you miss the middle.

You are accurate if you hit the middle, even if your hits aren't exactly close to one another.

In chemistry, accuracy is crucial because it ensures consistent outcomes.

To achieve the best results, accuracy and precision must be combined, though accuracy alone is not enough.

Minimize the number of variables that could influence your experiment and try to maintain as much consistency as you can to improve precision (and accuracy).

The degree of agreement or reproducibility of measurements made under similar conditions is known as precision in chemistry, and it represents the degree to which individual measurements agree with one another. A high degree of precision indicates that repeated measurements produce results that are similar, whereas a low degree of precision indicates significant variability among measurements.
