WebThe paired t-test calculator also called the dependent t-test calculator compares the means of the same items in two different conditions or any others connection between the two samples when there is a one to one connection between the samples - each value in one group is connected to one value in the other group. The test uses the t distribution. WebAs a general rule because the Folded F stat is a test of unequal variances, when the folded F statistic is large and the p-value is <0.05, as shown in the SAS output above, then we refer …
WebThis test is known as an a two sample (or unpaired) t-test. It produces a “p-value”, which can be used to decide whether there is evidence of a difference between the two population means. The p-value is the probability that the difference between the sample means is at least as large as what has been observed, under the assumption that the ...
