Surface Forms
Morphology
The compound is directly compositional: 'Gaussian' specifies the bell-shaped, symmetric form and 'distribution' names a frequency/probability spread, so their combination denotes a bell-shaped probability distribution. This structure is standard and mirrored in many languages (e.g. distribución gaussiana), so a learner who knows both constituent meanings would readily infer the MWE meaning.
Etymology
Gaussian distribution is named after the scientist Gauss and is often shown as a 'bell curve' with a tall middle and low sides. That's why it describes data where many values are near the average and only a few are far away.
