 Dear students, in this module we are going to talk about survey design using case study method. When we talk about research design we have seen that the quantitative data collected in the survey design is developed by generalisation based on that. लेकिन के स्टर्टी मातर्द जो है ये एक रिगुरस प्रोस्स होता है किसी एक फिनामिन्न को किसी एक पर्टिकुलर अस्पक्त को जानने के लिए उस्टर्री मातर्ट के लेना होता है तो हम के स्टर्टी मातर्ट के अंड़ ख़ाली टेटेग, क्वांतेटेटेग अबजर्वेशन अपड़िवूँँझसागे मातर्ट करते हुए प्रूट नध्ट नालास्ची के तरफ जाते है then identifying the key themes and patterns in the data because the data collected on a massive level and the qualitative and quantitative possibilities of the data can be of both kinds so we identify the key themes which are the aspects of the data and what can be the classification of them what can be the categorization of them what can be the key themes what can be the sub themes which we can interpret on the basis of this data then developing a rich and announced understanding of the case under study when it comes to interpretation obviously these interpretations are dependent on your theoretical framework or theoretical lenses you have to see that we are going to interpret these findings under which theoretical framework and how can we develop such an understanding and then assessing the strengths and limitations of this case study research obviously every research method has a limitation its strengths and weaknesses so in the same way we see that the case study method what are the limitations of this any phenomenon or any particular organization or while studying the group the limitations of this are also necessary as an example we can take for example conducting a case study on the experiences of Pakistani refugees living in the urban slums so whatever refugees who come to Pakistan who are living in urban slums let's suppose that they want to study the case study on the Afghan refugees they want to understand this expatriate behavior they want to understand this living pattern we want to see how a refugee's life is so you need to study comprehensive cases to focus on that aspect so in this way we can produce a relatively more reliable knowledge using a particular group's behavior on the case study method
