Test statistic Definition Calculation p-value degree of freedom ExampleAbout The t-test is a test that compares means. NHST can be conducted yielding to a p-value Effect Size can be calculated like in multiple regression. Confidence Interval around the mean can also be reported T-tests: ...

Means and standard deviations of all measurements were obtained. A t-test for paired samples was applied to identify statistical significance. The significance threshold was set at p ≤ 0.05. Since the data sets are approximately normally distributed, further statistical investigations are not ...
Statistical significance or p-value of t-test for testing mean difference has been widely used for the comparison of two groups. However, because of many issues that the statistical significance has, it has been intensively criticized in medical and social sciences. Consequently, effect sizes such...
aThe means of multiple groups were compared with one-way ANOVA, after the equal check of variance, and the two–two comparisons among the means were performed using the LSD method. Statistical comparison was also performed with two-tailed t-test when appropriate. P<0.05 was considered as statis...
Mehmet,Mende,Soner,Yiit 摘要: A Monte Carlo simulation was conducted to compare the type I error rate and test power of the analysis of means (ANOM) test to the one-way analysis of variance F-test (ANOVA-F). Simulation results showed that as long as the homogeneity of the variance ...
The result of the significance test in the principle component scores shows that all components of young female adults from both countries had some significant differences. It means that there were differences in the upper and lower body parts between the Korean and Japanese young female adults. ...
