the p-value would be 2 ∗ 0.1056, or 0.2112.. If the results are likely to have occurred under the claim, then you fail to reject H 0 (like a jury decides not guilty). If the results are unlikely to have occurred under the claim, then you reject H 0 (like a jury decides guilty). 0 (like a jury decides guilty).T-Distribution / Student’s T: Definition, Step by Step,,The t distribution is used instead of the normal distribution when you have small samples (for more on this, see: t-score vs. z-score). The larger the sample size, the more the t distribution looks like the normal distribution. In fact, for sample sizes larger than 20 (e.g. more degrees of freedom), the distribution is almost exactly like the normal distribution.Understanding Particle Size Distribution Calculations - HORIBA,Most instruments are used to measure the particle size distribution, implying an interest in the width or breadth of the distribution. Experienced scientists typically shun using a single number answer to the question “What size are those particles?”, and prefer to include a way to define the width.
