The paired t-test calculator calculates the paired t-test p-value. When you enter raw data, the paired t-test calculator also calculates the Shapiro-Wilk normality test and calculates the outliers. Enter raw data directly Enter raw data from excel ...
Paired Sample t-Test The calculator below implementspaired sample t-test(also known as adependent samples t-testor at-test for correlated samples). The t-test is also known as Student's t-test, after the pen name of William Sealy Gosset. Paired samples t-tests typically consist of a samp...
Preleminary test to check paired t-test assumptions Assumption 1: Are the two samples paired? Yes, since the data have been collected from measuring twice the weight of the same mice. Assumption 2: Is this a large sample? No, because n < 30. Since the sample size is not large enough ...

Test Statistic (t-score): t=¯¯¯xd−μd(sd√n)t=x¯d−μd(sdn)where: ¯¯¯xdx¯d is the mean of the sample differences. μd is the mean of the population differences. sd is the sample standard deviation of the differences. n is the sample size....
1C). Importantly, we found that the effects of age, gender, paired P-R sample IDs, and data source (paired P-R sample IDs and data source particularly) were much higher than the effects of longitudinal progression status and TTR on gene expression (Fig. 1C). Thus, to examine the ...
2.8. Sample size The sample size required to detect a comparable improvement was calculated using an online calculator from (http://hedwig.mgh.harvard.edu/sample_size/js/js_crossover_quant.html). Based on previous studies of paired neurostimulation for chronic pain [45], which reported a mean...

A total amount of 1 µg of RNA per sample was used as input material for the RNA library construction. In brief, rRNA was first removed from total RNA, and then the RNA was fragmented by sonication into 250–300 bp short fragments. The first strand of cDNA was synthesized with ...
A single-factor analysis of variance (ANOVA) with two-sample t-tests was conducted (Treated, n = 143; Untreated, n = 146) to evaluate the differences in percent foliar cover, litter cover, bare ground and the relative cover of each functional group throughout the watersheds. The difference...
