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...
Proportions were compared using a Fischer exact test and quantitative data was compared using a t-test. All tests were two tailed and a p value of <.05 was considered significant. This study was approved by the Institutional Review Board of National Institute of Tuberculosis and Respira- tory ...
The first grade, which represents the highest vulnerability, had a normalized vulnerability value of 0.8–1 (Fig. 1). After classification of the vulnerability grades, the first-grade maps were synthesized on the basis of each field. This was done for two reasons. The first is that the ...
The square-root of AVE is on the diagonal; lower-diagonal values are inter-construct correlations and upper-diagonal values are HTMT ratio of correlations * p < 0.05; **p < 0.001. Two-tailed significance values for Pearson correlation coefficient are reported C hhajer et al. ...
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 ...
Finally we compared each individual subject's LI to zero in a two-tailed t-test and plotted the distribution of p-values across simulations (O and P). The peak analysis drastically increased the false-positive error rate (at α = .05, 500 simulations should fall below 0.05, O), while ...
Closely related to this is the CHISQ.INV.RT function. This is the same as CHISQ.INV, with the exception that it deals with right-tailed probabilities. This function is particularly helpful in determining the critical value for a given chi-square test. All we need to do is to enter the ...
Think of a study that might test the hypothesis. Indicate whether you think the independent variable sho A researcher obtains t = 2.25 for a repeated-measures study using a sample of n = 10 participants. Based on this t value, what is the correct decision for...
Mesenchymal Stem/Stromal Cells (MSC) are a promising cell type for cell-based therapies - from tissue regeneration to treatment of autoimmune diseases - due to their capacity to migrate to damaged tissues, to differentiate in different lineages and to th
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 ...
