Stratifiserte

Stratifiserte is the past tense form of the Norwegian verb stratifisere, meaning that something has been divided into layers or strata. The root stratif- stems from the Latin strata, meaning layer, with the typical scientific formations stratifisere. The form stratifiserte is used in technical contexts to describe that stratification has been performed.

In statistics and research, to stratify a population means to partition it into homogeneous subgroups, or strata, based on characteristics such as age, geographic region, or other variables. Stratifiserte data or samples are those that have been organized in this way before sampling, which can improve the precision of estimates and ensure representation across key subgroups. Stratified sampling is a common method associated with this practice, and analyses may apply weights to reflect the size of each stratum.

In geology and sedimentology, stratification refers to the layering of rocks and sediments. A stratified rock shows distinct layers that reflect different depositional periods. The term stratifiserte can be used in field notes or descriptions to indicate that observations or samples have been organized according to layered structure.

In medicine, public health, and social science, stratification is used to classify individuals or data by risk, socioeconomic status, or other criteria. This helps tailor interventions, allocate resources, or study differences between layers of a population.

Overall, stratifiserte denotes that a prior process of dividing into layers has taken place, across disciplines where layered structure is central.
