Accuracy and precision are pretty confusing terms but you should know that they are different in many ways. I have come across many people using these two words in the same statement. These two words don't mean the same thing and I want you to distinguish the two terms from each other.
I have asked a lot of people to outline the difference between accuracy and precision and what I get to hear from them is shocking. Quite a large number believes that the two terms mean the same thing. They move ahead to outline that the words are commonly used in the validation of data. That is either in terms of its measurement or context. I want to end the whole confusion right now and right here! Read on!
A close outlook
The first way to look at the difference between accuracy and precision is by checking out the application of the terms. Accuracy in most of the instances usually points out to how close any particular measurement is to whatever is considered as the real or the accepted value.
A good way to look at this is by using weights. Take for instance a balancing undertaking where we expect the final reading to be 100 grams. That is upon the placement of a standard item that weighs 100 grams. Failure to give a correct reading of 100 grams could lead to the balance being described as inaccurate.
On the other hand, precision points out to an aspect in which a particular the results you gather or obtain remain consistently similar. That is even after engaging in repeated measurement acts.
The other distinguishing points in terms of the difference between accuracy and precision
Before I outline the other differences, it is notable that both the terms are very critical when it comes to calculations and measurements.
Why I’m I saying this? It is because these terms are crucial in helping us identify some of the underlying issues or errors in different cases. It is good understanding this point, but it is also important to know the difference between accuracy and precision.
The difference between accuracy and precision can be looked at from the aspect of the various factors in play. I mean that in the determination of accuracy we only need to check out one single factor, which isn't the case with precision. For the case of precision, you are required to consider some wide-ranging factors.
The evaluation bit is the next way we need to look at in understanding the difference between accuracy and precision. You should know that in the case of accuracy, only one measurement matters or is considered. Matters are different when it comes to the term precision and that is considering that it requires multiple measurements in the evaluation process.
Another important point in line with marking the difference between accuracy and precision is the targeted points and calculations. In the case of accuracy, you will be out targeting some particular points or things. In the case of precision, you will be focusing on calculations.
The difference between accuracy and precision is not something complex for you if you stay focused on learning. In showing you the difference between accuracy and precision, it is crucial to outline that the two terms are independent. In other words, I'm talking about the aspect that a particular measurement could be precise but not accurate. Similarly, a given measurement might turn out to be accurate, but not precise. I know that you find this complex, but with determination, you will eventually understand the difference between accuracy and precision.
