Frequently Asked Questions
A t-score (t-statistic) is a ratio of the difference between a sample mean and a population mean to the standard error of the sample mean. It is used in hypothesis testing to determine if there is a significant difference.
Degrees of freedom (df) for a one-sample t-test is the sample size minus 1. It reflects the number of independent values that can vary in the calculation.
The p-value is approximated using the cumulative distribution function of the t-distribution. For a two-tailed test, it is 2 times the probability of obtaining a t-value as extreme as the observed one.
