01 | Abstract: Sampling is one of the vital parts of any research process and also touches different aspects as translatability‚ comparability‚ Validity and totalization. When researchers use qualitative data‚ they first understand it and then try to explain it as the data is non-probabilistic and cannot be represented as easily as others. This paper studies the sampling procedure to know teaching learning relations for minority students in Botswana classrooms. Here‚ In this paper‚ researcher
