True or False: The null hypothesis is rejected if the p-value (i.e. the probability of getting a test statistic at least as extreme as the observed value) is greater than the significance level. If the test statistic for a difference o...
Critical values depend on your significance level and whether you’re performing a one- or two-sided hypothesis. For these examples, I’ll use a significance level of 0.05. This value defines how improbable the test statistic must be to be significant. Related posts:Significance Levels and P-v...
All tests were two tailed, and a P value of <.05 was considered statistically significant. Continuous variables are presented as mean ± SD and were tested using analysis of variance (ANOVA). Categorical data were expressed as numbers and compared, using the Fisher's exact test. Results A ...
The two-tailed P value equals 0.7698. Chi-squared equals 0.233 with 1 degree of freedom. The two-tailed P value equals 0.6295. The association between RFS and PEPSIN detection is considered to be not statistically significant.In terms of correlation analysis, neither the RSI nor the RFS had ...
The survey was followed by two experiments designed to test the effects of gear modifications on bird abundance and diversity. For bags, results indicated that shallow immersion (∼6 cm below surface) and floater instability were effective deterrents to P. auritus , reducing its abundance by a...
Differences in mean values were tested for significance using the independent 2 tailed t test for comparison between 2 groups. The X2 or Fisher exact test was used where appropriate for categorical data. Cox proportionate hazards models were used to analyze hazard ratios for patient, treatment, ...
for positive but not control trials at future retrieval, consistent with updating via reconsolidation. Comparison groups were the Immediate-test (n = 25) and No-reminder group (n = 24). Analyses were two-tailedt-tests. Overlaid dots represent individual participants. Bars show mean ...
1, 2, 3). One tailed Mann-Whitney test was used to compare two samples, whereas comparison between more than two samples was performed using the Friedman-matched paired test followed by Dunns comparison test. For grouped samples, two-way ANOVA test was used followed by Bonferroni post-test....
P value < 0.05, FDR < 0.01, and a fold change equal or greater than 2-fold were used as the screening cutoffs for determining extremely significant differential gene expression between two samples. Highly expressed isoforms with root-specific characteristics were used as ...
