The t value formula is a statistical tool used to determine the significance of a sample mean. It calculates the ratio of the difference between the sample mean and the known population mean to the standard error of the mean. This ratio, also known as the t-statistic, is then compared to a critical value from a t-distribution table or calculated using a t-distribution calculator.
