如果P- value大于0.05:你会说,“这个结果不算特别,我没有理由怀疑硬币不公平。” 总结来说,P- value能够告诉研究者,这个数据有多么不正常。而significance level,是用来判断“多不寻常”才真的不寻常的标准。
In hypothesis testing, if the p-value is less than the significance level, we ___. A. reject the null hypothesis B. fail to reject the null hypothesis C. accept the alternative hypothesis D. accept the null hypothesis 相关知识点: 试题...
However, you might be surprised to learn that higher p-values, the ones that are not statistically significant, are also valuable. In this post, I’ll show you the potential value of ap-valuethat is greater than 0.05, or whateversignificance levelyou’re using. The Role of Hypothesis Testin...

If P-value < a then we reject the null hypothesis and we say that the results are "statistically significant." Suppose that P-value = 0.02 and a = 0.05. Since the P-value is less than alpha we say: "We reject the null hypothesis at the 5% significance level."Some common critical ...
Powerful p-value calculator online: calculate statistical significance using a Z-test or T-test statistic (z test calculator / t-test calculator). ➤ P-value formula, Z-score formula, T-statistic formula and explanation of the inference procedure. Stat
I have also read that if the significance level I am seeking (and yes, I grok that is different than p-value) is 0.05 if you do enough experiments, the error rate will approach the alpha (significance level) If that could be also part of the example, I think folks would grasp this ...
P-value is the level of marginal significance within a statistical hypothesis test, representing the probability of the occurrence of a given event.
and the significant variables.The Fishers F-test with a very low probability value also demonstrates a very high significance for the regression model since the computed F value (F0:01(14;15)= S2r/S2e= 58.78) is much greater than the tabular F0:01(14;15) value (3.66) at 1.5% level....
