How do you calculate t value in statistics?
t-Test value is calculated using the formula given below t = ( x̄1 – x̄2) / √ [ (s21 / n 1 ) + (s22 / n 2 )] t = (10 – 12) /√ [ (1.2 2 / 17) + (1.4 2 / 15)] t = -4.31 Therefore, the absolute t-test value is 4.31, which is greater than the critical value (3.03) at a 99.5% confidence interval with a degree of freedom of 30.
