WebOct 20, 2024 · n: sample size (i.e. number of pairs) = 20 We will perform a paired samples t-test with the following hypotheses: H0: μ1 = μ2 (the two population means are equal) HA: μ1 ≠ μ2 (the two population means are not equal) Next, we’ll calculate the test statistic: t = xdiff / (sdiff/√n) = -0.95 / (1.317/√20) = -3.226 WebEffect Size Calculator for T-Test For the independent samples T-test, Cohen's d is determined by calculating the mean difference between your two groups, and then dividing the result by the pooled standard deviation. Cohen's d = ( M2 - M1) ⁄ SDpooled where: SDpooled = √ ( ( SD12 + SD22 ) ⁄ 2) Glass's Delta and Hedges' G
