Finding the Error Margin

To find the error margin, you need to consider the context in which you are calculating the error. The error margin is a measure of the uncertainty or variability in a measurement or calculation. It indicates the range within which the true value is likely to fall.

Here are a few common methods for finding the error margin:

1. Percentage Error: This method calculates the difference between the measured value and the true value as a percentage of the true value. The formula is:

   Percentage Error = (|Measured Value - True Value| / True Value) * 100
   

For example, if the measured value is 10 and the true value is 9, the percentage error would be:

   Percentage Error = (|10 - 9| / 9) * 100 = 11.11%
   

2. Absolute Error: This method calculates the difference between the measured value and the true value without considering the direction. The formula is:

   Absolute Error = |Measured Value - True Value|
   

For example, if the measured value is 10 and the true value is 9, the absolute error would be:

   Absolute Error = |10 - 9| = 1
   

3. Relative Error: This method calculates the absolute error as a fraction or ratio of the true value. The formula is:

   Relative Error = Absolute Error / True Value
   

For example, if the absolute error is 1 and the true value is 9, the relative error would be:

   Relative Error = 1 / 9 = 0.1111
   

These are just a few methods for finding the error margin. The choice of method depends on the specific context and requirements of your calculation or measurement.
