unstratified

Not arranged hierarchically

Unstratified describes something not arranged in layers or strata.

The term appears most often in geology, where unstratified rock or soil lacks the distinct horizontal bands that result from gradual deposition: The glacial till was unstratified, a jumbled mass of boulders and clay.

In statistics and social science, unstratified sampling or data hasn't been divided into subgroups for analysis.
