Accurate and precise measurements are essential to developing a mixture. Whether you’re using pitchers, containers, or cups for measurement, ensuring the product delivers reliable and consistent results protects the safety of the consumer.
How To Determine Measurement Accuracy vs Precision
In order to identify if product measurement is accurate and precise, it’s vital to understand the difference between the two terms.
What Is Accuracy?
Accuracy is how close a measurement conforms to a unified standard. In other words, accuracy refers to the closeness of a measured value to a universally or industrially understood known value. For example, suppose you only obtain 2.5 ounces of a substance for a mixture that requires 2.8 ounces. In that case, your chemical is not accurate because it has a deficit of 0.3 ounces of needed material.
What Is Precision?
Precision—also referred to as the “repeatability of the variation”—ensures that a final product or mixture acquires the same result every time without generating random errors. For example, if you continue to measure 2.5 ounces of a substance after measuring it three or four times, the measurement is precise.
How To Measure Accuracy
When working with hazardous chemicals, measuring products with a significant degree of accuracy is crucial to developing a safe mixture. It’s essential to determine the deviation to determine the accuracy of a measurement. Here are the steps to ensure high accuracy:
- Collect as multiple measurements of the needed material
- Find the average value of your measurements
- Find the absolute value of the difference of each measurement from the average
- Determine the average of all the deviation by adding them up and dividing by the number of measurements
How To Measure Precision
In addition to accuracy, precision is essential to ensuring each measurement is correct every time so there are no inconsistencies in performance or mixture results. Precision is determined by standard deviation, which is how much and how often measurements differ from one another. If a standard deviation is high, then it suggests low precision. On the other hand, if a standard deviation is low, then it suggests high precision.
