How to Calculate Percent Error with Example

Math with Mr. J

This educational video provides a clear, step-by-step tutorial on calculating percent error, a critical concept in mathematics and science for determining the accuracy of measurements. The narrator, Mr. J, begins by defining percent error as a method to evaluate how accurate a measurement or estimation is compared to an actual value. He presents the formula explicitly: the absolute value of the measured value minus the actual value, divided by the actual value, all multiplied by 100.
