GraphPad QuickCalcs: t test calculato P<0.05 or P>0.05 but don't tell you the exact value of P StatMate will calculate P (to four decimal places) from t, z, F, r, or chi-square It will also calculate a P value from the results of the runs test, sign test, and McNemar's test

GraphPad QuickCalcs: t test calculator Performs unpaired t test , Weldh's t test (doesn' t assume equal variances) and paired t test . Calculates exact P value and 95% confidence interval.

There is normally a separate table for t values to use in a one tail test . http://www.graphpad.com/quickcalcs/OneSampleT1.cfm? found that 93.5% of the reports were observational, and the chi-square test was most frequently used, followed by logistic regression and Student's t-test to analyze them.

The GRIM (Granularity‐Related Inconsistent Means) test, which was developed by James Heathers and Nicholas Brown, flags impossible mean values. 8 For example, if pain is rated on a 0‐10 integer scale, and the study has 10 participants, then the mean must contain an even tenth—for example, 4.00, 5.10, or 6.30—because the mean is a whole number divided by 10. I used t-tests to compare the means of the two groups. I examined associations between suicide rate and demographic and health data by province using Pearson Correlations. I used principal components analyses (PCA) and non-metric multidimensional scaling (NMDS) plots to compare the variables found to significantly correlate with suicide rates. The Levene's tests perform an ANOVA test over the absolute deviations from each group's average or the absolute deviations from each group's median.

T-test was performed with the QuickCalcs t test calculator (https:// · www. graphpad.com/quickcalcs/ttest2/). The STA Cephascreen aPTT reagent showed good
