accuracy is how close the value is to the true value. precision is how close the measurements are to one another. when something is accurate, it is almost exact in its measurement. precision measures the closeness of each value is to each other. refer to the picture that shows the visual representation if that helps!
Accuracy is defined as how close to the exact amount your measurement was, in other words, how close and correct you were. And Precision is defined as the consistency and closeness of your measurements. Its important to have both when conducting experiments.
Accuracy measures the validity of your measurement, or how close you were to the actual values to be obtained. Precision on the other hand measures the replicability of your results, or how many times you got the same result. If your method of experimenting stays the same throughout multiple trials, you will likely achieve similar results with each experiment, meaning your precision is high.
A good way to see the differences between accuracy and precision is to refer back to the picture of accuracy v precision that he had on his lecture slides, it really helps to distinguish between the two visually.
