Hence we can see that how large or how small the T statistic is depends on how close or far away the sample mean is from the hypothesised mean. If the sample mean is close to hypothesised mean, we will get a T statistic close to zero. Whereas if the sample mean if far away from t...
For a hypothesis test that has null hypothesis $H_0 : \mu_1 = \mu_2$, the value of the test statistic is determined by the formula $$t=\frac{\bar X_1-\bar X_2}{\sqrt{\frac{\sigma_1^2}{n_1}+\frac{\sigma_2^2}{n_2}}}$$ where $\bar X_1$ and $\bar X_2$ are...

“统计数据”是statistic,这是由于人们将调查后的数据立(t)在那就成了“统计数据”。另外,我们再看看T的形状,它竖立在那也会“触”到上面的屋顶,因此“接触”就是touch。tango(探戈舞)是我们比较熟悉的一类舞蹈,就需要两个舞伴互相“接触”着进行。所以,tangible(可触知的,有形的)也含有字母T。 含义:从字母...
