Population and sampling scheme
WebThe population of the study was all the lecturers in the six federal universities in South-South Nigeria. The sample consisted of 579 lecturers in four selected universities established before the introduction of Contributory Pension Scheme. A multistage stratified random sampling was used in selecting the sample size of the study. WebSuch side uses cookies toward store information on your home.

WebJun 17, 2008 · We were interested in the effects of sampling schemes on population clustering when the population was randomly mating and when there was an underlying neighbor mating scheme. Therefore, we established a series of six different sampling schemes reflective of how samples are collected in the conservation genetics and … WebFor some studies, the population may be small enough to warrant the inclusion of all of them in the study. But a study may entail a large population which cannot all be studied. That portion of the population that is studied is called a sample of the population (Nworgu 1991:69). A sample in this study is, therefore, a smaller group
