UNCERTAINTY CHEMISTRY CALCULATOR HOW TO

More details on how to propagate the errors here. Now, to calculate the uncertainty for V, you first try to calculate the uncertainties for D and H, and then apply the propagation of errors technique on them. Suppose that you have the formula V= 1/4 x pi x D^2 x H, and your entire experiment is to measure D and H such that you can then use them to calculate V. And since max-min/2 (or range/2 method if you will) measures the spread of the data, so we use it to measure random errors. Random errors are usually caused by random factors originated from the equipment, human errors (like when pressing the stop button of a stop watch), or just random changes in the environment, which means that random errors can cause a spread in the measurements of the same variable. Nope, the max-min/2 method is not for systematic error.

So for random error do i JUST calculate the % uncertainty for each apparatus (apparatus uncertainty/measured value x100) and then add them together? what else am I supposed to do? HELP I calculated the uncertainty for raw data using max-min/2 (what my teacher told me) this is for systematic error.
