Or, if you want to test whether the average weight before treatment is greater than the average weight after treatment, type this t.test(weight ~ group, data = my_data, paired = TRUE, alternative = "greater") Interpretation of the result The p-value of the test is 6.210^{-9}, which...
Step 6: Use the conclusion of the t-test to give an interpretation in the context of the setting of the specific problem. Paired t test example Question: Assume that you have the following sample of paired data. Sample 1 Sample 2 Difference = Sample 1 - Sample 2 4 2 2 5 3 2 6 ...
We’ll use the pipe-friendlyt_test()function [rstatix package], a wrapper around the R base functiont.test(). The results can be easily added to a plot using theggpubrR package. stat.test <- mice2.long %>% t_test(weight ~ group, paired =TRUE) %>% add_signific...
Enhancement: The interface should state if a variable is Measure 1 or Measure 2. Purpose: Simplify choice of Alt. Hypothesis for one-tailed paired t-tests, and its interpretation. Is your feature request related to a problem? Please desc...
Last, if you compute difference scores, you can circumvent the paired samples t-tests altogether: instead, you can run one-sample t-tests on the difference scores with zeroes as test values. The syntax below does just that. If you run it, you'll get the exact same results as from the...

Interpretation By looking at the ‘Significantly different? (P<0.05)’ output, a ‘Yes’ is given which essentially means that our results are significantly different from each other. The exact p value is given next to ‘P value’. In this case a p value of < 0.0001 indicates a very sig...
(Fig. 1). If the amount of presented information is not too large, amnesic patients can perform well on the immediate recall test, but they invariably fail after the delay. The usual interpretation of this finding has been that immediate (short-term) memory is intact in amnesia and ...
3A). Results from single-sample gene set enrichment analysis (ssGSEA) further showed that metastatic lesions had higher immune scores (median 838.6 vs 644.3, P = 0.01, paired t test, Fig. 3B), compared to paired primary lesions. But there was no significant difference between metastatic ...
5C and Hi-C datasets can be used quantitatively to investigatechromosome structure, given that each element in an interaction maps can be interpreted as being proportional to the contact probabilities of the associated chromosomal loci[16]. A natural consequence of this interpretation is that the com...
