The t-statistic, which is used in statistics, measures how far a parameter's estimated value deviates from its hypothesised value relative to its standard error. Through the Student's t-test, it is utilised in hypothesis testing. In a t-test, the t-statistic is used to decide whether to accept or reject the null hypothesis. The t-statistic is used when the sample size is small or the population standard deviation is unknown. It is quite similar to the z-score in other respects. Once the standard deviation is unknown, the t-statistic is in use, for one, to approximate the population mean from a sampling distribution of sample statistics.
