== Similar concepts ==
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 <math>d=\frac{\bar{X}_1 - \bar{X}_2}{\text{SD}}=\frac{\bar{X}_1 - \bar{X}_2}{\sigma}=\frac {t} {\sqrt N}</math> and is related to the [[test statistic]] <math>t</math> in the [[t-test]].<ref>{{cite web |url=https://blog.minitab.com/en/adventures-in-statistics-2/understanding-t-tests-1-sample-2-sample-and-paired-t-tests |title=Understanding t-Tests: 1-sample, 2-sample, and Paired t-Tests |access-date=2024-08-19}}</ref>
