In the first example, we use a matched-pairs design to compare the number of errors made on a driving course when a small sample of people drive distracted versus not distracted. In the second example, we use a matched-pairs design to test whether a coping skills program reduces stress ...

To test a sample mean from one group of cases against that from another group of cases, use the Independent-Samples T Test. If you want to compare a sample mean against a constant value, use the One-Sample T Test. If the data in the test variable are not quantitative, but ordered...
An independent sample t test was used to measure the differences between groups at baseline, and between-group differences in changes in MVPA. The within-group changes in outcomes and MVPA over time were assessed using paired t tests. General linear models (GLMs) were applied to evaluate the ...
An independent-sample t-test was used to analyze quantitative variables. With R software (version 4.0.3), ROC curve analysis and Kaplan–Meier survival analysis were used to evaluate the accuracy of predicting survival outcomes. Cox proportional models were used to examine the relationship between ...

The width of the lines represents the number of RCTs for each pairwise comparison, and the size of each node is proportional to the number of randomized participants (sample size). The yellow lines represent trials with unclear or high risk of allocation concealment, and the green lines ...
Statistical tests were performed with IBM SPSS software (Version 23.0, Chicago, IL, USA). Shapiro-Wilk and Levene’s tests were used to confirm the normal distribution and the equality of variances, respectively. We used a two-tailed dependent sample t-test to examine whether relative muscle ef...

We assume that we have a training set to fit the model and a test set to check the out of sample performance. First, the individual relevance of each variable is computed by comparing the predictions in the test set, given by the model that includes all the variables with those of ...
