Marginalized Knowledge: An Agenda for Indigenous Knowledge Development and Integration with Other Forms of Knowledge

4.5 Sample frame and sample size
Neuman (2006:201) argues that a researcher ‘operationalizes’ a population by developing a specific list that closely approximates all the elements within the population. This list is the sampling frame. According to Delvin (2006:56), the sample size will be drawn from this frame. The sample size constitutes making a judgment about the number of participants needed to carry out the research. Therefore, although there are twenty-three public universities in South Africa (Wikipedia 2007,Current official South African Universities Section, par.2), only the following four were selected purposively for this study:

• 
  University of Kwa-Zulu Natal
  
• 
  University of Zululand
  
• 
  Durban University of Technology
  
• 
  Mangosuthu Technikon
  

In Kenya there are seven public universities (Wikipedia 2007, Current official Kenyan Universities section, par.2). However, only the following three were selected purposively for this study.

 

• 
  Nairobi University
  
• 
  Moi University
  
• 
  Masinde Muliro University of Science and Technology 
  

 

The sample size consisted of all the academic librarians that were working in these universities and holding Bachelors, Masters or Doctorate degree.
