Percent error measures the accuracy of a value by comparing the difference between an experimental (or observed) value and a true (or accepted) value, expressed as a percentage of the true value. It is calculated using the formula:
`\text{Percent Error} = \left( \frac{|\text{Experimental Value} - \text{True Value}|}{\text{True Value}} \right) \times 100\%`
This topic is important for evaluating the precision of experimental results in various scientific and mathematical contexts.
