Statistics
Significance quick-test (t)
Welch's t-test for two groups: p-value, effect size, and a plain verdict.
t = (x̄_A − x̄_B) / √(s_A²/n_A + s_B²/n_B)
Replicate measurements for condition A (2 or more).
Replicate measurements for condition B (2 or more).

Welch's t✓ t = (x̄_A − x̄_B) / √(s_A²/n_A + s_B²/n_B)
p = 0 (a significant difference at α = 0.05)
