anor277 answered · 1 month ago 2 Answers Suppose you are going to measure the length of a pencil in centimeters. answered · 1 month ago 1 Answer How would you minimize errors of measurements in the lab? The true value is the textbook/literature value. If you get the same answer every time, you've got a precise measurement.

If it is greater than the true value, the percent error will be positive. (experimental value) − (true value) % error = ――――――――――――― 100 true value Things get spilled, things are impure, equipment is imprecise... Without "Absolute Value" We can also use the formula without "Absolute Value".
