There are four different research strategies: inductive, deductive and less used, reproductive and abductive. The aim of the inductive approach is to 'establish universal generalizations to be used as explanations of models', while the deductive approach is 'to test theories, to eliminate false ones'. The latter would construct and 'deduce hypotheses' rather than 'produce generalisations' (Blaikie, 2007) - appendix for table. The topic was the theory developed by Atkinson as the “center-periphery model”. The model highlighted that companies are likely to retain “core” workers, while the periphery includes low-skilled and inexperienced employees, whose numbers run parallel to business fluctuations and identified that low-skilled workers would fit the model from further deductive research . (Atkinson & Torrington, 1984; 2004). However I emphasize that this model was not a direct theory to be tested deductively, there were flaws in the model, since applied, as the name suggests, to the periphery, which is not specific enough to my answer, so it would be better to decide to do inductive reasoning as a justifying choice. In addition, the method, also known as "bottom-up", also requires fewer tests, but more observation methods. (Dunn & Wickham, 2012) All in all, deductive reasoning will create a theory with observations. Grounded theory is applied to the inductive reasoning approach. “Grounded Theory is a research strategy whose purpose is to generate theory from data” (Punch, 2014). It is about how the data will be analyzed to create a theory, through the use of Grounded Theory. This grounded theory is more about how humans have learned, and according to Glaser (1967), the grounded theory is right… halfway through the article… their contribution to research. A guiding principle is that participants must have control over the disclosure of their identity and contribution. Since the University prevents research under 18 years of age, there are other venerations in groups where it was not realized that a disability, such as dyspraxia, existed. which is not a physical disability. After reviewing the principles of ethics considered in social research, there are many factors that should be applied to research, if anything, this is the most important, as ethics should determine research. The biggest flaw in all of this is young people: make sure they are over 18, even though young people can be 16 years old. Employers express their thoughts about their reasons and make sure they do not break the law by converting it into a generalization. idea that might be illegal and therefore unethical.
