cohort

Examples of cohort in the following topics:

• Methods for Researching Human Development

  • In a longitudinal study, a researcher observes many individuals born at or around the same time (a cohort) and carries out new observations as members of the cohort age.
  • This method can be used to draw conclusions about which types of development are universal (or normative) and occur in most members of a cohort.
  • Also, because members of a cohort all experience historical events unique to their generation, apparently normative developmental trends may only be universal to the cohort itself.
  • A researcher observes members of different birth cohorts at the same time, and then tracks all participants over time, charting changes in the groups.
  • Microgenetic design studies the same cohort over a short period of time.

• The Asch Experiment: The Power of Peer Pressure

  • Variations of the basic paradigm tested how many cohorts were necessary to induce conformity, examining the influence of just one cohort and as many as fifteen.
  • Results indicated that one cohort has virtually no influence and two cohorts have only a small influence.
  • When three or more cohorts are present, the tendency to conform increases only modestly.
  • The maximum effect occurs with four cohorts.
  • Adding additional cohorts does not produce a stronger effect.

• Introducing observational studies and experiments

  • For instance, researchers may collect information via surveys, review medical or company records, or follow a cohort of many similar individuals to study why certain diseases might develop.

• Confounding

  • In cohort studies, a degree of matching is also possible, and it is often done by only admitting certain age groups or a certain sex into the study population. this creates a cohort of people who share similar characteristics; thus, all cohorts are comparable in regard to the possible confounding variable.

• What Does One Of These Have To Do With The Others?

  • Another approach to the idea of learning communities at a college or university level is the implementation of cohorts.
  • The instructor's role in a cohort is that of a facilitator.
  • The particular learning community depicted here is the University of Georgia's School Library Media Cohort System.

• Widespread Belief

  • One study categorizes white evangelicals, 26.3% of the population, as the country's largest religious cohort, while another study estimates evangelicals of all races at 30–35%.

• Interactive Whiteboards

  • At the same time, however, the BECTA (UK) commissioned a study into the impact of interactive whiteboards over a two-year period and showed very significant learning gains, particularly with second cohorts of students, who benefited from the teacher's experience with the device.

• Semicolons

  • Example: Of these patients, 6 were not enrolled; thus, the cohort was composed of 141 patients at baseline.

• Dr. Miller's Pharmacy Class

  • She had joined a study group with her cohort.

• Analytical Mindset
