I mis-worded that. I do understand that the standard deviation of the measurement is the random error, but I'm wondering how I'm actually supposed to calculate it (as easy at that sounds). Let's say for example that my mass measurements have an uncertainty of +/- 0.05g and the measurement is...

I do in fact have measurement errors, but how would I derive the random error using standard deviation?

I'm currently in first year engineering and I seem to be struggling with Physics, which is not unlikely uncommon. A simple problem I've come across is not doing correct error analysis when writing up lab reports. In my current lab, which is justifying the relationship of angular frequency...
