The protected Fisher's LSD test Protectionmeans that you only perform the calculations described above when the overall ANOVA resulted in a P value less than 0.05. If the P value for the ANOVA is greater than 0.05 (or whatever significance level you set), you conclude that the data are con...
(false positive) error rate. Stat-Ease, Inc. chooses to maximize the power of detecting true effects while allowing the family-wise type I error rate to grow slightly larger than the alpha significance cutoff. If decisions are based on a falsely positive effect, future experiments and ...

All data were subjected to analysis of variance and means were compared at the 0.1 significance level using Fisher's protected least significant difference (LSD) test.A. E. RobertsonJ. Shriver... A. E. Robertson,J Shriver - 《Plant Disease Management Reports Pdmr》 被引量: 1发表: 2015年 ...
The significance level, also denoted as alpha or α, is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicatesa 5% risk of concluding that a difference exists when there is no actual difference. ...
How much must two means differ before we can consider the difference "real" and not due to chance? To answer this question, we must use a. coefficients of correlation. b. tests of statistical significance. c. graphical statistics. d. random...

When a hypothesis of the equality of several means is tested by using ANOVA and it is rejected for a given level of significance, Least Significant Difference (LSD) test is most commonly applied to know which mean(s) is(are) significantly different from which. This procedure usually becomes ...
Fisher's LSD procedure is known to preserve the experimentwise type I error rate at the nominal level of significance, if (and only if) the number of treatment groups is three. The procedure may therefore be applied to phase III clinical trials comparing two doses of an active treatment ...
