3.2 Sample Size and Sampling Technique
The sample would consist of traditional herbal medical practitioners selected from the three states of the South West Geo-political Zones. The states are Ekiti, Osun and Oyo. Five hundred and t
hirty would be considered appropriate for this study because traditional herbal medical practitioners are few in number and sparsely located (Ajao, 2015).
Multi-stage sampling techniques would be adopted at different stages of sampling geo-political zone, states and representative samples for this study. At the first stage, purposive sampling technique would be used to select geo-political zone (South West), at the second stage random sampling technique would be used to select three states from six states which constitutes south west geo political zone. The states that have highest concentration of herbal medical practitioners from different ethnic groups would be selected since there are specialization such as Sickle cell anemia healer, Traditional Psychiatricians, Traditional Orthopaedician, Traditional Gynaecologists, Traditional Pediatricians and General traditional medicine practitioners among others. At the third stage, stratified sampling technique would be used to select 530, traditional herbal medical practitioners from Ekiti, Osun and Oyo states in the South West Geo-political Zone.
