Percent error is typically used to describe the difference between an expected value and an observed value (measured in an experiment). To calculate percent error, you must know the expected (or theoretical) value, determined from reference manuals and formulas.
Percent error = [(actual measured value)/(expected value) - 1] x 100%
Let's say that you do a chemistry experiment, where you expect to use 30 mL of a hydrochloric acid solution to neutralize a prepared solution of sodium hydroxide.
When you perform the experiment, you actually use 30.2 mL of hydrochloric acid solution.
Percent error = [(30.2 mL) / (30 mL) - 1] x 100% = 0.667 % error

What is the difference between the low percent error and the high percent error?
If it's high that means it's very off and away from the actual value. If you find a low percent error it is very close or close to the true value.
What number is 15 percent out of 290?
To find 15 percent of 290, you can multiply 290 by 0.15. This calculation gives you 43.5. Therefore, 15 percent of 290 is 43.5.
How do you calculate the percentage error in a measurement or calculation?
To calculate the percentage error in a measurement or calculation, you first find the difference between the measured or calculated value and the accepted or true value. Then, divide this difference by the accepted value and multiply by 100 to get the percentage error. The formula is: Percentage Error (Measured Value - Accepted Value / Accepted Value) x 100
