'You want to draw a representative sample of social workers employed in domestic violence programs. You have a list of all such programs, but not of their staff members. Your survey will involve face-to-face interviews, and your travel budget is limited to visiting 10 cities. What kind of sampling design would you use.

Given the limited travel budget and the goal of drawing a representative sample of social workers employed in domestic violence programs, you could consider using a stratified random sampling design. Here's how you might approach it:

1. Stratification:

• Divide the list of domestic violence programs into strata or groups based on relevant characteristics. For example, you might stratify by city or region, ensuring representation from different geographic areas.

2. Random Sampling within Strata:

• Randomly select programs from each stratum. This ensures that you have representation from various cities or regions, preventing bias that may arise if you only sample from a single area.

3. Program Inclusion Criteria:

• Before selecting programs, establish inclusion criteria to ensure that the selected programs meet certain qualifications. This could include factors such as program size, the number of social workers employed, or the duration of the program's existence.

4. Random Selection of Social Workers:

• Once programs are identified, randomly select social workers from each chosen program to participate in face-to-face interviews. This step helps ensure that the social workers within each program have an equal chance of being included.

5. Adjustments for Proportions:

• If the number of social workers in each program varies significantly, you may consider adjusting the number of social workers selected from each program to achieve a more proportionate representation.

6. Data Collection:

• Conduct face-to-face interviews with the selected social workers in the chosen cities. Ensure that the interviews are structured and standardized to maintain consistency across participants.
