Health Management Information System (HMIS)
A Health Management System (HMS) refers to a structured system for collecting, processing, analyzing, and using health data to improve healthcare service delivery, policy-making, and patient outcomes. It helps in decision-making, resource allocation, and performance monitoring of healthcare programs.

| Non-Probability Sampling (Members are selected based on researcher’s judgment) | Convenience Sampling | Individuals are selected based on easy availability. |
| Purposive (Judgmental) Sampling | Individuals are chosen based on specific criteria. | |
| Snowball Sampling | Participants recruit more participants. | |
| Quota Sampling | Specific quotas of different groups are included in the sample. |
✅ Reduces cost and time in large population studies.
