那p已经小于a 那pvalue越大不是应该拒绝的a越大吗 那不就说明evidence更强吗

NO.PZ2018062016000136

问题如下:

According to the evidence of rejecting the null hypothesis, which of the following statements is most accurate?(Assume that the level of significance is represented by α)

选项:

A.

When the p-value is lower than α, the p-value is higher, the evidence is stronger.

B.

When the p-value is higher than α, the p-value is lower, the evidence is stronger.

C.

When the p-value is lower than α, the p-value is lower, the evidence is stronger.

解释:

C is correct. The p-value is the smallest level of significance(α) at which the null hypothesis can be rejected for a given value of the test statistic. The p-value is lower, the evidence of rejecting the null hypothesisthe is stronger.

那p已经小于a 那pvalue越大不是应该拒绝的a越大吗 那不就说明evidence更强吗

​同学你好, 这里的理解是α是固定的,在这个基础上,P<α就拒绝原假设,并且规律是“p越小越拒绝”。这个规律是要求记忆的。
