Quizplus · Accepted Answer

The t-statistic is calculated by dividing the difference between the means of two groups by the standard error of the mean, which measures the variability of the sample means around the true population mean. The larger the difference between the means and the smaller the standard error, the larger the t-value, indicating a greater likelihood that the observed difference is not due to chance.
