This paired t-test calculator deals with mean and standard deviation of pairs. Other t-test applications Often times you have two samples that are not paired, in which case you would use a t-test for two independent samples calculator. Notice that in that case the samples don't have to...

Now, to test the null hypothesis and find out if the mean difference is zero, you must: First, calculate the difference between the two observations for every pair of data(di=yi–xi).You must do this while ensuring that you distinguish between positive and negative differences. ...
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 VAS reduction of ...
