Step-by-Step Guide to Error Analysis

Step 1: Identify the Error

The first step in error analysis is to identify the error. This involves analyzing the steps taken to arrive at a solution and identifying any mistakes or inaccuracies.

Step 2: Evaluate the Error

Once the error has been identified, the next step is to evaluate the error. This involves assessing the impact of the error on the solution and determining the cause of the error.

Step 3: Correct the Error

The final step in error analysis is to correct the error. This involves revising the solution and ensuring that it is accurate and reliable.

Example: Error Analysis in Coordinate Geometry

Problem

Emilia was asked to find the coordinates of $D_2(\triangle ABC)$ for $A(2, 4)$ , $B(0, 5)$ , and $C(-2, 1)$ .

Solution

To find the coordinates of $D_2(\triangle ABC)$ , Emilia used the following steps:

Find the midpoint of $AB$ : $(\frac{2+0}{2}, \frac{4+5}{2}) = (1, 4.5)$
Find the midpoint of $BC$ : $(\frac{0+(-2)}{2}, \frac{5+1}{2}) = (-1, 3)$
Find the midpoint of $AC$ : $(\frac{2+(-2)}{2}, \frac{4+1}{2}) = (0, 2.5)$
Find the coordinates of $D_2(\triangle ABC)$ : $(\frac{1+(-1)}{2}, \frac{4.5+3}{2}) = (0, 3.75)$

Error Analysis

Emilia's error was in the calculation of the midpoint of $AB$ . She incorrectly calculated the midpoint as $(1, 4.5)$ instead of $(\frac{2+0}{2}, \frac{4+5}{2}) = (1, 4.75)$ .

Corrected Solution

To correct the error, Emilia revised the solution as follows:

Find the midpoint of $AB$ : $(\frac{2+0}{2}, \frac{4+5}{2}) = (1, 4.75)$
Find the midpoint of $BC$ : $(\frac{0+(-2)}{2}, \frac{5+1}{2}) = (-1, 3)$
Find the midpoint of $AC$ : $(\frac{2+(-2)}{2}, \frac{4+1}{2}) = (0, 2.5)$
Find the coordinates of $D_2(\triangle ABC)$ : $(\frac{1+(-1)}{2}, \frac{4.75+3}{2}) = (0, 3.875)$

Conclusion

Error analysis is an essential skill in mathematics that involves identifying, evaluating, and correcting errors in mathematical calculations, proofs, and problem-solving. It is crucial for ensuring the accuracy and reliability of mathematical work and developing problem-solving skills and critical thinking. By following the step-by-step guide to error analysis, mathematicians and scientists can identify and correct errors in their work, ensuring the accuracy and reliability of their results.
