问一道题:NO.PZ2018062016000131

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.

老师好,significant是指significantly different from*****吗?谢谢!

@leozhenlin

significant是显著的意思,这句话就是假设检验的结果显著的和原假设的设定不同。

但这么理解还是抽象,建议就把significant直接理解为拒绝原假设就行

同学你好,

理解正确

老师,我晕球了,the result is statistically significant.到底是啥意思,关键是statistically significant翻译过来中文是什么。

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?
