Like many statistical procedures, the paired sample t-test has two competing hypotheses, the null hypothesis and the alternative hypothesis. The null hypothesis assumes that the true mean difference between the paired samples is zero. Under this model, all observable differences are explained by rando...

As you will see from the next example, the analysis of paired samples is done by looking at the difference between the two measurements. As a result, this case uses the same techniques as for the one-sample case, although usually, it is easier to use either the paired t-test data analy...
In this experiment, we have provided three sources of evidence for the existence of a persistent form of procedural interference. First, we found significant levels of intrusions occurring in the last two stages of the transfer test. Such intrusions cannot be explained merely in terms of the tran...
aActually, when I was a new English teacher, I tried my best to make my students practice the patterns time after time, I hoped that they would get high marks in test. However, my students didn't care about it, they showed less attention to my class. [translate] aNext is organizing...
Procedure. The participants entered the laboratory in pairs and sat on chairs in front of the experimental materials, and the experimenter explained the procedure. Participants practiced tapping to obtain appropriate intensity with a good signal-to-noise ratio prior to beginning the trials. During...
The p-values are calculated using a two-sample one-sided student’s t-test in R. (H) Pearson correlation coefficients between miRNA and target gene expression (top panel), RNA-seq data (middle panel) and gene expression evaluated by RT-qPCR (lower panel) for the top four miRNA-target ...
A paired-sample t test was used to compare PPF at both 50-msec and 100-msec ISIs. PPF measured at 5 min pre-LFS was compared with PPF measured at 30 min post-LFS. For the 50-msec lSI, a sig- nificant decrease in facilitation was found at 30 min post- LFS when compared with ...
Last week, I was on my way home from the CAST conference with my 17 year-old son Oliver when a client called me with an emergency assignment: “Get down to L.A. and test our product right away!” I didn’t have time to take Oliver home, so we bought some clean clothes, had Oli...
