Situation

The recent monsoon has affected the Sindh province particularly Karachi which recorded the heaviest rainfall measuring 74.3mm. Rain floods have affected the residential and commercial areas, damaging properties and disrupting the power and telecommunication system. The intensity of the rain is likely to be increased and continued for the next few weeks. The Pakistan Meteorological Department (PMD) wants to collect data from the people who got injured by the recent rain floods in the residential areas of Karachi. The purpose is to list the hardships, financial losses, and dislocation of families.

PMD in this regard has hired the services of a researcher to conduct a study and collect data from such people. Quick and efficient data is required in this regard. Initially, the researcher tried to collect the data from unions and hospitals in the affected areas in order to gather data but, both entities showed non-corporation and reluctance to provide the list of people because of security and privacy reasons. The list of people is also incomplete thus the dataset was not reliable.

While keeping issues of difficulty in accessing people due to destroyed infrastructure and lack of data, the researcher is planning to collect the data from the affected people who are easily available by directly visiting the hospital wards.

The results of the study will be of utmost importance for the PMD to take immediate necessary actions for the affected people.

Being a student of Research, you are required to answer the following questions:

1. Which Non-Probability Sampling Technique should be adopted by the researcher in the given scenario? 2. Give two justifications in this regard.
