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]).
