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。
Does the higher the p-value mean more significance? For example, is p = 0.7 more significant than p = 0.05? The P-value of a hypothesis test is 0.0345. Which of the following claims is correct? Explain the answer. A) Reject H0 at the 0.05 significance level but not the 0.01 signif...

In hypothesis testing, if the p-value is less than the significance level, we do not have sufficient evidence to reject the null hypothesis. True or False? Explain in detail.The probability that we would get our observed result if the null hypot...
The p-value in reality is higher than the calculated p-value when the assumption of equal variances is violated. In other words, the probability of making a Type I error is actually larger than calculated. If you are assuming equal variances, then this assumption should be tested (similar to...
I find statements (1) and (2) contradictory because of the following. In making the decision about whether to reject the null hypothesis one compares the p-value to the significance level. (If pvalue is lower than the preset significance level one rejects the null hypothesis). It is possibl...
The FDR is very different from a p-value, and as such a much higher FDR can be tolerated than with a p-value. In the example above a set of 100 predictions of which 70 are correct might be very useful, especially if there are thousands of genes on the array most of which are not...

. It is a selected cut off point that determines whether we consider a p-value acceptably high or low. If our p-value is lower than alpha we conclude that there is astatistically significant difference between groups. When the p-value is higher than our significance level we conclude that ...
