The assignment discusses the importance of public health services in communities, highlighting the need for effective healthcare systems. A telephonic survey is conducted to gather opinions from residents on their demographic profiles and experiences with local health centers. The survey uses simple random sampling, which has advantages such as ease of implementation and unbiased representation. However, it also has disadvantages, including potential issues with homogeneous populations or widely spread units. The questionnaire provided includes questions on age group, gender, family size, monthly income, educational qualification, use of healthcare services, satisfaction with services, factors preventing immediate health services, and specific health services required.
