How to Use the Calculator
- Enter the Observed Value in the first input field. This is the actual value you have measured or obtained.
- Enter the Expected Value in the second input field. This is the true or target value that you were aiming for.
- Click the Calculate button to compute the percentage accuracy.
- The calculator will display the accuracy percentage, absolute error, and an accuracy status.
Understanding the Results
The calculator provides three key results:
- Accuracy Percentage: This is the percentage difference between the observed and expected values. It is calculated as [(Expected Value - Observed Value) / Expected Value] * 100%.
- Absolute Error: This is the absolute difference between the observed and expected values, showing how far off the observed value is from the expected value.
- Accuracy Status: Based on the accuracy percentage, the calculator categorizes the accuracy as High Accuracy (≤5%), Moderate Accuracy (5.1%-10%), or Low Accuracy (>10%).
Example
Example 1: If you expected a result of 100 but observed 95, the accuracy would be calculated as:
[(100 - 95) / 100] * 100% = 5% (High Accuracy)
Example 2: If you expected a result of 100 but observed 110, the accuracy would be calculated as:
[(110 - 100) / 100] * 100% = 10% (Moderate Accuracy)
Practical Applications
This calculator is useful in various fields including:
- Quality Control: Measuring the accuracy of production processes.
- Scientific Research: Evaluating experimental results.
- Finance: Assessing the accuracy of financial forecasts.
- Education: Measuring student performance against expected outcomes.
