Take the difference between your experimental value and your known value, and divide that difference by your know value.
Say you experimentally found the force of gravity to be 8m/s2, and you know that the true/known value is 9.8 m/s2, the percent error would be
l 8 - 9.8 l = 0.1836 or 18.36%
9.8

To determine how right or wrong their answer is.
Percent error refers to the percentage difference between a measured value and an accepted value. To calculate the percentage error for density of pennies, the formula is given as: percent error = [(measured value - accepted value) / accepted value] x 100.
Percentage error = Value experimental-Value acceptedValueaccepted x 100
