Ohort

Ohort is not a widely recognized term in standard English and is typically considered a misspelling or variant of the word cohort. In most scholarly and practical contexts, the intended term is cohort, which refers to a group of people who share a defining characteristic and are observed over a period of time.

A cohort is defined by a common attribute or experience, such as birth year, geographic location, exposure to a factor, or participation in a program. The concept is used across disciplines to study development, outcomes, and change over time. In epidemiology and public health, a cohort study follows a group to assess how exposures influence the incidence of diseases or other outcomes. Cohorts can be prospective, following participants forward in time, or retrospective, using existing records. The aim is to identify associations while accounting for potential confounding factors.

In business and analytics, cohort analysis groups customers by a shared starting point, such as the month of signup, and tracks their behavior over time. This method helps measure retention, lifetime value, and engagement, and is valuable for evaluating the impact of product changes or marketing campaigns on specific groups.

In education and social sciences, a cohort may refer to a group of students progressing through a program together or to generation-based cohorts used to study cohort effects—how the timing of experiences affects outcomes across generations.

Because ohort is not a standard term, most references will redirect to cohort or explain the discrepancy as a typographical error.
