Research Sampling Methods: Probability vs. Non-Probability Techniques
Probability and Non-Probability Sampling Methods
Probability (Random) Sampling
Probability sampling, also known as random sampling, is a method where the probability of being selected is known, meaning every member of the wider population has an equal chance to be included. The primary aim is for generalizability and wide representation.
Purpose and Example

Understanding Major Health Conditions and Risk Factors
Genetic Diseases and Their Causes
A genetic disease is a disorder caused by an alteration in a gene, known as a mutation. These mutations can occur randomly or as a result of exposure to certain environmental risk factors, such as tobacco smoke.
Environmental Factors Affecting Health
Environmental factors, such as certain chemicals, air pollution, or allergenic substances, also play an important role in the occurrence of diseases and the expression of certain genes.
Key Environmental Factors:
- Exposure
Literary Movements: Romanticism, Theory, and American Fiction
Rationalism Versus Romanticism: Core Differences
The conflict between Rationalism and Romanticism can be summarized by these opposing concepts:
- Reason / Emotion
