The signal-to-noise ratio is similar to Cohen's d given by the difference of estimated means divided by the standard deviation of the data d = X ¯ 1 − X ¯ 2 SD = X ¯ 1 − X ¯ 2 σ = t N {\displaystyle d={\frac {{\bar {X}}_{1}-{\bar {X}}_{2}}{\text{SD}}}={\frac {{\bar {X}}_{1}-{\bar {X}}_{2}}{\sigma }}={\frac {t}{\sqrt {N}}}} and is related to the test statistic t {\displaystyle t} in the t-test.
