Paired t-test can be used only when the differenceddis normally distributed. This can be checked usingShapiro-Wilk test. Related Book: Practical Statistics in R for Comparing Groups: Numerical Variables Research questions and statistical hypotheses ...
NCSS Statistical Software Paired T-Test NCSS.com Example 1 – Running a Paired T-Test This section presents an example of how to run a paired t-test as well as other paired comparisons. The data for this example are the tire data shown above and are found in the Tire dataset. The two...
The input data for the paired-sample t-test can have missing data, indicated by empty cells or cells with non-numeric data. Such cells will be ignored in the analysis. Example 2: Repeat Example 1 using the data in range B24:C39 of Figure 6. ...
Both can be used to compare how a static group performs in varying test conditions. The difference is that the paired t-test is used when the independent variable has two levels. Repeated measures ANOVA is used when the independent variable has more than two levels. So, for example, if ...

paired t-test when there are 2 variables and we want to test whether they differ (ttest varname1 == varname2). However, the way my data is set up after performing the matching doesn't have 2 separate variables. For example, there is 1 column for each measured characteristic, an ...
Alternative isoforms often differed in binding modalities, in many cases switching between dependent binding types (cooperative and antagonistic) (Fig. 4a, b, see Supplementary Table 13 within the Supplementary Data file). For example, while the STAT1-202 isoform showed cooperative binding with IRF9...
For example, TNFα signaling and inflammatory response genes both demonstrated significant trends toward upregulation in participants with HIV, a finding that accords well with prior work on macrophage inflammation and may be linked to changes in macrophage plasticity, which has been previously reported...
