Can my p value be 0
Web$\begingroup$ 0.04993 < 0.05, so it's just lower. Your instinct is good that no P-value can be trusted to several decimal places, but if the program says less than 0.05, people generally take it as delivered. WebDec 13, 2024 · In order to use the p-value in hypothesis testing, follow the steps below: Determine your level of significance (α). The level of significance generally should be chosen during the first steps of the design of a hypothesis test. The most common levels of significance include 0.10, 0.05, and 0.01. Calculate the p-value.

WebJan 18, 2024 · P Value of 0 is rare but theoretically possible. However in reality, p value can very rarely be zero. Any data collected for some study are certain to be suffered from … WebA low p-value provides statistical evidence to reject the null hypothesis—but that doesn't prove the truth of the alternative hypothesis. If your alpha level is 0.05, there's a 5% chance you will incorrectly reject the null hypothesis.
WebFeb 26, 2024 · Yes, it looks like your p-values are all greater than 0.05. I can’t tell if you have 31 observations per group, or split between groups.

WebMar 2, 2024 · @sirisha since your p-value is smaller than 0.05 you can reject null hypothesis that there's unit root (i.e. your data doesn't have unit root after transformation). 0.05 is standard, although you could go to 0.01 or 0.001 and still be happy because your p is MUCH less than that. – dm2 Mar 2, 2024 at 17:59 1 WebNov 27, 2024 · A p-value simply tells you the strength of evidence in support of a null hypothesis. If the p-value is less than the significance level, we reject the null hypothesis. So, when you get a p-value of 0.000, you should compare it to the significance level. …
WebP-values on standard computers (using IEEE double precision floats) can get as low as approximately 10 − 303. These can be legitimately correct calculations when effect sizes are large and/or standard errors are low. Your value, if computed with a T or normal distribution, corresponds to an effect size of about 31 standard errors.
