Suppose a normal distribution has a mean of four and a standard deviation of 1.75. What is the z-score of x=3.5? How does the p value relate to the two-tailed hypothesis in this table ? t-test:Two sample Assuming Unequal Variances | | Variable 1|Variable 2 |...
通过把所得到的统计检定值,与统计学家建立了一些随机变量的概率分布(probability distribution)进行比较,我们可以知道在多少%的机会下会得到目前的结果。倘若经比较后发现,出现这结果的机率很少,亦即是说,是在机会很少、很罕有的情况下才出现;那我们便可以有信心的说,这不是巧合,是具有统计学上的意义的(用统计学的...

When you perform at-test, you check if your test statistic is a more extreme value than expected from thet-distribution. For a two-tailed test, you look at both tails of the distribution. Figure 3 below shows the decision process for a two-tailed test. The curve is at-distribution with...
