WebApr 16, 2024 · I want to perform t-test (two-sided, unpaired, unequal variance) between Normal and Group1, Normal and Group2, and Normal and Group3 such that I get p.value for each gene. The t.test function in R returns single p.value and not gene-wise (I don't want to do t-test in Excel). Which package/function should I use to do this in R? WebApr 24, 2024 · Calculate the T-statistic. Subtract the population mean from the sample mean: x-bar - μ. Divide s by the square root of n, the number of units in the sample: s ÷ √ (n). Take the value you got from subtracting μ from x-bar and divide it by the value you got from dividing s by the square root of n: (x-bar - μ) ÷ (s ÷ √ [n]).
