问一道题:NO.PZ2018062016000131 [ CFA I ]

问题如下:

In the steps of hypothesis testing, which of the following descriptions on the statistically significant result is most accurate?

选项:

A.

When we test the null hypothesis, the caculated value of the test statistic is less extreme than a given value.

B.

When we accept the null hypothesis, we can get a statistically significant result.

C.

When we reject the null hypothesis, the result is statistically significant.

解释:

C is correct. When we test the null hypothesis, if we find that the calculated value of the test statistic is as extreme or more extreme than a give value or values determined by the specified level of sigificance, we reject the null hypothesis, we say the result is statistically significant.

请问b选项是说反了吗?

同学你好,

首先一般很少用“accept” the null这种说法,但这道题的关键还是如果无法拒绝原假设,说明并不significant

C is correct. 当计算出来的检验统计量的绝对值大于临界值(criticvalue)的绝对值时,拒绝原假设,并简称为statistically significant A的意思不就是当测试值小于关键值的时候,我们要接受原假设吗?A为什么不对呢?

请问A错在哪?是不是错在当我们test,可能有两个结果(大于或小于临界值,并不一定像说的小于)? 另外请问given value一定指临界点吗?如果given value指临界值,是有可能正有可能负还是指绝对值?
