Age Groups:

Example: Stratifying by age groups such as 18-29, 30-49, 50-64, and 65+.

Discussion: Age is often associated with different life stages, interests, and needs. By stratifying by age groups, you can ensure representation from various segments of the adult population, allowing for more accurate estimates and comparisons within each age cohort.

Education Level:

Example: Stratifying by educational attainment, such as high school diploma or less, some college or associate degree, bachelor's degree, and postgraduate education.

Discussion: Education level can influence perspectives, behaviors, and access to resources. Stratifying by education level allows for examining how attitudes, preferences, and behaviors may differ across educational backgrounds.

Income Levels:

Example: Stratifying by income brackets, such as low-income, middle-income, and high-income households.

Discussion: Income level reflects socioeconomic status and can impact lifestyle, access to services, and consumption patterns. Stratifying by income allows for studying variations in attitudes, behaviors, and preferences based on economic circumstances.

2. 4- part time

16- full time

3. Regional Stratification: Divide the country into major regions (e.g., Luzon, Visayas, Mindanao) and then further stratify each region into smaller areas (e.g., provinces, cities, municipalities).

4. Collaboration with Local Community Leaders: Collaborate with local community leaders, village heads, or barangay officials to gain insights into the demographics of the area and to seek their assistance in identifying potential participants.

5. Over-represented groups- tourist

Under-represented groups- local residents.

7. When looking to draw attention to your project and attract participants for a self-selected sample, you can employ various strategies to increase visibility and engagement. Here are some ways to do so: online platforms, word of mouth, and partnership and collaboration.

Despite the advantages of self-selection in terms of convenience and ease of recruitment, the main disadvantage is the potential for bias in the sample. Since participants choose whether or not to participate in the study, there is a risk of self-selection bias.
