## About Percent Deviation Calculator (Formula)

The Percent Deviation Calculator is a valuable statistical tool used to quantify the difference between an observed value and an expected or theoretical value as a percentage of the expected value. This calculator is commonly used in scientific research, quality control, and data analysis to assess the accuracy and variability of measurements.

The formula for the Percent Deviation Calculator involves calculating the absolute difference between the observed and expected values, dividing it by the expected value, and then multiplying by 100 to express the result as a percentage:

**Percent Deviation = |(Observed Value – Expected Value) / Expected Value| * 100**

To use the calculator, you need to know both the observed value and the expected value.

Inputting these values into the formula allows you to calculate the percent deviation, which indicates how much the observed value differs from the expected value as a percentage.

The Percent Deviation Calculator is essential for assessing measurement accuracy, identifying outliers, and evaluating data quality in various scientific and industrial applications.

Researchers, quality control professionals, and analysts find the Percent Deviation Calculator invaluable for validating experimental results, ensuring product consistency, and making informed decisions based on data variability.
