Chapter 206 Two-Sample T-Test
Two-Sample T-Test Introduction This procedure provides several reports for the comparison of two continuous-data distributions, including confidence intervals for the difference in means, two-sample t-tests, the z-test, the randomization test, the Mann-Whitney U (or Wilcoxon Rank- Sum) nonparametric test, and the Kolmogorov-Smirnov test.

Chapter 575 Probit Analysis - Statistical Software
ncss-wpengine.netdna-ssl.comChapter 575 Probit Analysis Introduction Probit Analysis is a method of analyzing the relationship between a stimulus (dose) and the quantal (all or nothing) response. Quantitative responses are almost always preferred, but in many situations they are not practical. In these cases, it is only possible to determine if a certain response (such as ...

For a two-sample test, if each sample is 20 to 25 or over that is often good enough. But it depends on how non-normal the data is. If the data are strongly non-normal, you might need a larger sample size, say 50 or even ...

www.cis.upenn.eduBecause events are subsets of the sample space W, they can be combined using the set operations, union, intersection, and complementation. If the sample space W is finite, the definition for the probability Pr(A) of an event A W given in Definition 5.1 shows that if A,B are two disjoint events (this means that A\B= 0),/ then Pr(A[B)=Pr(A)+Pr(B).
