In practice, the significance level is stated in advance to determine how small the p-value must be to reject the null hypothesis. Because different researchers use different levels of significance when examining a question, a reader may sometimes have difficulty comparing results from two different ...
The t-distribution example shown above is based on a one-tailed t-test to determine whether the mean of the population is greater than a hypothesized value. Therefore the t-distribution example shows the probability associated with the t-value of 2.8 only in one direction (the right tail of ...

Recommended P-value VideoWhy P = 0.05?Click here to read an excellent description on the reasoning why 0.05 was selected as the general criteria to determine statistical significance. A p-value of 0.05 or lower is generally considered statistically significant but may not be suitable for every ...
Thanks to the graph, we were able to determine that our results are statistically significant at the 0.05 level without using a P value. However, when you use the numeric output produced bystatistical software, you’ll need to compare the P value to your significance level to make this dete...

P值(p-value)是指当原假设为真时,检验值与原假设之间的差异出现的概率。P值的大小通常用来衡量样本数据与原假设之间的偏离程度,较小的P值表示样本数据与原假设之间的差异越大,这意味着原假设越不可信,应该被拒绝。通常情况下,如果P值小于事先设定的显著性水平(如0.05),则可以拒绝原假设;反之,如果P值大于显著...
