WebAs before, it can be reversed to determine the sample size needed for a given difference to be statistically significant. So, for example, to detect a difference of 7% points, a sample size of about 400 is needed. In practice, samples in the n = 400 range are often taken as an acceptable default, as error reduction begins diminishing beyond that.

WebApr 12, 2016 · As a rough rule of thumb, we use a measurement gap which is 5-10 times larger than the large (st) particle size (i.e. D95) in the sample. With a gap this size, the chance, even at higher rotational speeds, of the particles physically jamming together (like a traffic jam!) is slim so that we can ensure we are measuring the bulk material flow.
