How do you calculate accuracy?
To calculate accuracy, you need to compare the number of correct or accurate results with the total number of measurements or observations made. The formula for calculating accuracy is:
Accuracy = (Number of Correct Results / Total Number of Measurements) * 100
Here’s a step-by-step guide on how to calculate accuracy:
- Determine the total number of measurements or observations you have made.
- Identify the number of correct or accurate results obtained.
- Divide the number of correct results by the total number of measurements.
- Multiply the result by 100 to convert it into a percentage.
For example, let’s say you conducted an experiment where you measured the boiling point of water multiple times and obtained the following results:
Trial 1: 99°C (Correct)
Trial 2: 98°C (Incorrect)
Trial 3: 100°C (Correct)
Trial 4: 99.5°C (Correct)
In this case, you have a total of four measurements, and three out of four are correct. Applying the formula:
Accuracy = (3 / 4) * 100 = 75%
Therefore, in this scenario, your accuracy is calculated as 75%.
It’s important to note that accuracy is always expressed as a percentage and represents how close your measurements are to the true value or accepted reference value. A higher accuracy percentage indicates greater precision and reliability in your measurements.
What are the two types of accuracy?
The two types of accuracy commonly referred to in measurement and data analysis are:
1. Absolute Accuracy: Absolute accuracy refers to the degree of closeness between a measured value and the true or accepted reference value. It represents how accurately a measurement reflects the actual quantity being measured, without considering any systematic or random errors that may be present. Absolute accuracy is often expressed as an absolute error or the difference between the measured value and the true value.
2. Relative Accuracy: Relative accuracy, also known as precision, relates to the consistency and repeatability of measurements taken under similar conditions. It assesses the degree of agreement among multiple measurements of the same quantity. While relative accuracy does not directly measure how close a measurement is to the true value, it provides information about the consistency and reliability of a measuring instrument or method.
Both absolute accuracy and relative accuracy are important considerations in different contexts. Absolute accuracy focuses on minimizing errors and ensuring that measurements are as close to the true value as possible. On the other hand, relative accuracy emphasizes precision, highlighting the consistency and reproducibility of measurements over multiple trials or observations.
It is worth noting that achieving high levels of both absolute and relative accuracy can be challenging as they often involve trade-offs. Increasing absolute accuracy may require more sophisticated equipment or calibration processes, while improving relative accuracy usually involves reducing random errors through repeated measurements or statistical techniques.
By understanding these two types of accuracy, practitioners can make informed decisions about measurement methods, instruments, and data analysis approaches based on their specific requirements and objectives.

What is an example of accuracy?
An example of accuracy can be found in the field of sports, specifically in target shooting competitions. In disciplines such as archery or rifle shooting, accuracy is measured by how closely the shots hit the center of the target. The closer the shots are to the bullseye, the higher the level of accuracy.
For instance, imagine a competitive archer aiming at a target 70 meters away. Through consistent practice and honing their skills, they release their arrows with precision and achieve remarkable accuracy. If most of their arrows consistently hit within a small radius around the center of the target, they can be considered highly accurate.
In this context, accuracy is determined by how closely the actual results align with the intended goal or target. It showcases the archer’s ability to control factors such as aim, release technique, and consistency in order to consistently hit their desired mark.
This example illustrates that accuracy extends beyond numerical measurements and can be observed in various fields where achieving precision and hitting targets with consistency are essential.
