Likelihood Memes

Everyone's got deviance all wrong! While women picture handcuffs (kinky or criminal?), and men imagine furry conventions (no judgment here!), statisticians are sitting in the corner like "ACTUALLY, it's a likelihood ratio test measuring how far observed data deviates from a null hypothesis." The mathematical formula at the bottom is statistical deviance in all its nerdy glory - twice the difference between log-likelihoods under different parameter estimates. Next time someone mentions "deviant behavior," just whip out this equation and watch their eyes glaze over faster than experimental data points on a scatterplot!
