In particular, for a given real (not necessarily integer) value n of the number of degrees of freedom, we give a pair of power series approximations for the inverse, F−1 n , of the cumulative ...

T-Distribution: This type of sampling distribution is common in cases of small sample sizes. It may also be used when there is very little information about the entire population.

The distribution is shorter and wider than the typical distribution and enables more outlying measurements. The distribution moves towards a classic normal curve as the number of measurements ...

The first column in Table 2 denotes the width of the sample distribution expressed at the sGSD. ... The D10, D50, and D90* as a function of number of particles analyzed, are shown in Table 3 and ...
