1. Given this information, what would be the overall sample size?

The overall sample size is 105, 600 (completed interviews)

2. How many households would have to be visited?

621, 177 households to be visited

3. What do you think of this estimated sample size?

The sample size is very large.

4. How feasible will it be to conduct this survey?

Likely not to be feasible given logistics (training, preparation, timing of visits, number of teams), costs and time. Discussion with steering committee on priorities is needed.

5. What are the trade-offs in terms of time, money, and quality of survey implementation

There is an ongoing trade-off between precision at a granular level, the operational costs of implementing and quality of survey implementation.

A larger sample size will have higher precision but with large costs and be time consuming. Reducing sample size will reduce the precision but could result in better quality of results and be more feasible in terms of operational costs.

Quality is inversely proportional to size of survey- larger field effort over longer period of time can compromise quality. Sample size is biggest driver of costs including number of teams, training, preparation, supervision etc.
