  • Degree of Freedom Calculator for T-test |StatCalculator. net
    Two-Sample T-Test (Unequal Variance): If n 1 = 10, s 1 = 3 2, n 2 = 12, and s 2 = 2 8, the degrees of freedom can be calculated using Welch's formula One-Sample T-Test: If n = 25, then df = 25 − 1 = 24

  • Degrees of freedom for 2 samples with unequal variance (t-test)
    Is it possible for the degree of freedom to be more than the number of observation for an unpaired hypothesis test? I am doing t-Test: Two-Sample Assuming Unequal Variances with sample size of 11 for each data set However when I am calculating the df using excel data analysis tool I am gettin df = 19? How is this possible?

  • 11. 2 - When Population Variances Are Not Equal | STAT 415
    Recall that if you have two independent samples from two normal distributions with unequal variances σ X 2 ≠ σ Y 2, then: T = (X ¯ − Y ¯) − (μ X − μ Y) S X 2 n + S Y 2 m follows, at least approximately, a t r distribution where r, the adjusted degrees of freedom is determined by the equation:
