Echogenicity (sometimes as echogenecity) or echogeneity is the ability to bounce an echo, e.g. return the signal in medical ultrasound examinations. In other words, echogenicity is higher when the surface bouncing the sound echo reflects increased sound waves.

Assessing the homogeneity of the population would involve looking to see whether the responses of certain identifiable subpopulations differ from those of others. For example, car-owners may differ from non-car-owners, or ...
