Therefore, p = 0.73 means that there's a 0.73 probability of finding an absolute mean difference of at least 0.71 points. Roughly speaking, the sample mean we found is likely to occur if the null hypothesis is true.Effect SizeThe only effect size measure for a one-sample t-test is ...
For one sample t-tests, how to interpret a standardized score in terms of its direction and distance from the mean? T-Test: The T-test is a type of statistical test that can be used to test the mean difference between two groups. There are se...
假设2和假设3称为 one-tailed tests one-sample t-test 计算公式：We can compute the p-value corresponding to the absolute value of the t-test statistics (|t|) for the degrees of freedom (df): df=n−1. 如何理解这个结果？ 如果p-value小于等于显著水平0.05，这个...

Paired Samplettest Thepaired samplettestis used to compare the means of two related groups of samples. Put into other words, it is used in a situation where you have two values (i.e., a pair of values) for the same group of samples. Often these two values are measured from the same...
Often, a nullhypothesis, which means no difference in your data from a zero effect. A zero effect indicates that a factor, like an intervention or medical treatment does not have any effect. The one sample t-test is adequate for assessment....
