STAT6000: Designing a Public Health Survey: Data & Techniques

This assignment provides a detailed solution to designing a short telephone survey aimed at identifying demographic characteristics of individuals within a local community health service's catchment area, differentiating between those who utilize the service and those who do not. The solution discusses potential sources of population data, such as government census records, NGO data, and previous research, evaluating the advantages and disadvantages of each. It advocates for stratified sampling to ensure the sample accurately reflects the population's key demographic attributes and outlines methods for participant recruitment, emphasizing informed consent. The assignment also includes a comprehensive questionnaire with closed and open-ended questions designed to gather relevant data on service usage, demographics, and user experiences, utilizing Likert scales for subjective assessments. This resource is available on Desklib, offering students access to a variety of solved assignments and study tools.

PART A
The intention of conducting a telephonic survey is to find statistically significant
demographic differences between the two groups who tend to avail the community health
service and those who choose not to avail the same. The population information potentially
may be derived on account of below mentioned sources.
 Government Census & Records – Relevant information can be obtained from the
records maintained with the relevant local government under whose jurisdiction the
community falls. Also, for the beneficiaries the implementing agency can provide
valuable data (Medhi, 2015).
The main advantage would be that the underlying data would be accurate, reliable and
available without any hassle. However, the downside would be the standard nature
owing to which suitable changes may be required. Additionally, the data may not
highlight the data differently for those availing the service and others who do not use
the community health service (Hastie, Tibshirani & Friedman, 2016).
 Relevant Non-Government Organisations – Owing to involvement of NGO in the
implementation of various community level programs, thus customised relevant data
may be obtained from a relevant NGO active amongst the target population (Hillier,
2016)
The obvious advantage is that custom data relevant to the study can be easily obtained
but this custom data may at times lack reliability and thus adversely impact reliability
which is a key disadvantage (Hastie, Tibshirani & Friedman, 2016).
 Previous Research – It might be possible that the relevant data can be derived from
past research on the target population (Medhi, 2015).
The benefit is that the requisite data can be obtained without expenditure of time and
resources but the downside is that the data may be old and relevant in a context
different from the researcher (Hillier, 2016).

The sampling technique of choice in this case will be stratified sampling. This is because it
tends to ensure that the sample for the two groups closely reflects the population in terms of
key demographic attributes which require comparison here. For recruitment of participants,
either direct advertisements targeted to the population of interest may be floated or the
process can be completed by coordination by a local NGO active amongst the population of
interest (Hillier, 2016). The informed consent of the participants would play a crucial role in
the process as it is necessary for each participant. Further, the advantage of the NGO led
method would be with regards to obtained representative samples but can involve time and
resources. A relatively quicker way could be direct contact through advertisement but the
sample obtained may lack attributes similar to the population of interest Lind, Marchal &
Wathen,2016)
