P value using t stat

WebMar 6, 2024 · A p-value, or probability value, is a number describing how likely it is that your data would have occurred by random chance (i.e. that the null hypothesis is true). The level of statistical significance is often expressed as a p -value between 0 and 1. The smaller the p-value, the stronger the evidence that you should reject the null hypothesis. WebMay 10, 2024 · The T.DIST function returns the left tail of Student’s t-distribution. This function can also be used to obtain the y -value for any point along the density curve. The T.DIST.RT function returns the right tail of Student’s t-distribution. The T.DIST.2T function returns both tails of Student’s t-distribution.
