What distinguishes probability sampling from non-probability sampling ...
Probability sampling stands out from non-probability sampling methods by ensuring that every item in the universe has an equal chance of being selected for the sample. This method allows researchers to calculate error margins, determine confidence levels, and estimate the required sample size for achieving desired levels of accuracy in their findings.

What distinguishes probability sampling from non-probability sampling ...
Understanding Probability Sampling
Probability sampling is a method where each member of the population has a known, non-zero chance of being selected. This method is crucial for ensuring that research findings can be generalized to the broader population.
Key Characteristics of Probability Sampling:
- Equal Chance of Selection: Every individual has an equal opportunity to be chosen, which minimizes bias.
- Statistical Validity: The method allows for accurate estimation of population parameters and the calculation of margins of error.
- Random Selection: Techniques like simple random sampling, stratified sampling, and cluster sampling are commonly used.
Understanding Non-Probability Sampling
In contrast, non-probability sampling does not provide every individual with a chance to be selected. This can lead to biases, making generalizations less reliable.
Key Characteristics of Non-Probability Sampling:
- Subjective Selection: Researchers may choose participants based on convenience or judgment, rather than randomness.
- No Statistical Validity: It does not allow for accurate generalization to the entire population.
Why Option C is Correct
Option 'C' states that "Probability sampling involves every item in the universe having an equal chance of selection." This is the defining feature that sets it apart from non-probability sampling. By ensuring that every individual has an equal chance, probability sampling enhances the reliability and validity of research findings.
Conclusion
In summary, the core distinction lies in the method of selection. Probability sampling ensures equal opportunity for selection, which is essential for statistical analysis and generalizations, unlike non-probability sampling methods.
