Outlier Identification
... An approximate two-sided P-Value is obtained by computing the probability of exceeding |T| based on Student’s t-distribution with n - 2 degrees of freedom and multiplying the result by 2n. A small P-value leads to the conclusion that the most extreme point is indeed an outlier. For small samples, on ...

... statistic. The degrees of freedom (df) for this example is 27, which is n – 1 (where n = number of pairs). For our example we had 28 pairs – and when we subtract the one restriction – we get df = 27. The Sig. provides the actual probability level for our example, which is shown to be .000 (i.e., < . ...

Fitting Experimental Data to Straight Lines (Including Error Analysis)
... All the above equations assumed that each data point had the same amount of absolute (not relative) error associated with it. This is rarely the case in practice. It is much more common for relative errors to be similar, or for errors to be larger at the extreme ends of the measurement range. In any ...

... This is random sampling with a system! From the sampling frame, a starting point is chosen at random, and thereafter at regular intervals. For example, suppose you want to sample 8 houses from a street of 120 houses. 120/8=15, so every 15th house is chosen after a random starting point between 1 and ...
