High t stat meaning
In statistics, the t-statistic is the ratio of the departure of the estimated value of a parameter from its hypothesized value to its standard error. It is used in hypothesis testing via Student's t-test. The t-statistic is used in a t-test to determine whether to support or reject the null hypothesis. It is very similar to the z-score but with the difference that t-statistic is used when the sample size is small or the population standard deviation is unknown. For example, the t-statistic is used in estimatin… WebMay 1, 2011 · A high z-score (or t-score, depending on what info you've been given for the data) means that a number is very far away from the mean (average) number.

WebMar 6, 2024 · A p -value higher than 0.05 (> 0.05) is not statistically significant and indicates strong evidence for the null hypothesis. This means we retain the null hypothesis and reject the alternative hypothesis. You should note that you cannot accept the null hypothesis; we can only reject it or fail to reject it. WebApr 3, 2024 · Degrees of freedom are the number of values in a study that have the freedom to vary.
