The number of tails:We need to know whether our t-test is one-tailed or two-tailed because we will use the respective one-tail or two-tail row to mark the alpha level. The alpha levels are listed at top of the table (0.50, 0.25, 0.20, 0.15…for the one-tail and 1.00, 0.50, 0....
T-Distribution Table (One Tail). For more info on the parts of the t table, including how to calculate them, see: degrees of freedom and alpha level.
T Distribution Table - Explore the T Distribution Table for statistical analysis. Understand degrees of freedom and critical values for accurate data interpretation.
Describe the relationship between the Z table and the standard normal distribution table. Formulate a probability statement to determine the value of z so that the area under the standard normal curve in the left tail is 0.0377. If a population distribution has an average...
Step 1: Subtract onefromyour sample size. This will be your degrees of freedom. Step2: Look up the dfinthe left hand side of the t-distribution table. Locate the column under your alpha level(the alpha levelisusually given to youinthe question). ...
What Does a T-Distribution Tell You? Tail heaviness is determined by a parameter of the t-distribution calleddegrees of freedom, with smaller values giving heavier tails, and with higher values making the t-distribution resemble a standard normal distribution with ameanof 0 and astandard deviation...

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...
