Lag time and hysteresis (systematic) - Some measuring devices require time to reach equilibrium, and taking a measurement before the instrument is stable will result in a measurement that is generally Kick Images, Getty Images By Anne Marie Helmenstine, Ph.D.

The actual mass is 218 grams. The following are some examples of systematic and random errors to consider when writing your error analysis. It is helpful to know by what percent your experimental values differ from your lab partners' values, or to some established value. A similar effect is hysteresis where the instrument readings lag behind and appear to have a "memory" effect as data are taken sequentially moving up or down through a range of

Error calculation is not possible, unless you make a quantitative measurement of the various quantities involved in your experiment.
