How to know if you reject or accept the null
Web4 mrt. 2024 · When performing a hypothesis test, you set the threshold for concluding significance, say at 0.05 or 0.1. If the p-value is less than the threshold, then you reject the Null hypothesis. You cannot make a statement like "I am 95% confident the null hypothesis is false". The validity of the null hypothesis is judged by the p-value … WebIn the context of how t-tests work, you assess the likelihood of a t-value using the t-distribution. If a t-value is sufficiently improbable when the null hypothesis is true, you can reject the null hypothesis. I have two crucial points to explain before we calculate the probability linked to our t-value of 2.
