The document outlines the essential characteristics of a good sample in research, highlighting features such as representativeness, absence of sampling errors, and practical utility. It emphasizes the importance of economic viability and goal orientation, as well as the need for random selection to ensure the sample accurately reflects the population. These characteristics aim to enhance the reliability and applicability of research findings.

- 4. Characteristics of a Good Sample • Representativeness • Absence of sampling error • Economically viable • Generalized and applicable • Goal oriented • Proportional • Randomly Selected • Actual information provider • Practical
- 5. Characteristics of a Good Sample 1. Representativeness • A researcher selects a relatively small number for a sample from an entire population. • This sample needs to closely match all the characteristics of the entire population. • It will help generalize the results from a small group to large population being studied.
- 6. Characteristics of a Good Sample 2. Absence of sampling error • Sampling error is the error caused by taking a small sample instead of the whole population for study. • Sampling error is reduced by selecting a large sample and by using efficient sample design and estimation strategies.
- 7. Characteristics of a Good Sample 3. Economically viable • Studies have a limited budget called the research budget. • The sample should be done in such a way that it is within the research budget and not too expensive to be replicated
- 8. Characteristics of a Good Sample 4. Generalized and applicable • Samples that it covers the whole population of the study and is not limited to a part.
- 9. Characteristics of a Good Sample 5. Goal oriented • A sample should be goal oriented. • It is means and should be oriented to the research objectives and fitted to the research conditions.
- 10. Characteristics of a Good Sample 6. Proportional • A sample should be proportional. • It should be large enough to represent the population properly. • The sample size should be sufficiently large to provide statistical stability or reliability. • The sample size should give accuracy required for the purpose of particular study.
- 11. Characteristics of a Good Sample 7. Randomly Selected • A sample should be selected at random. • This means that any item in the group has a full and equal chance of being selected and included in the sample. • This makes the selected sample truly representative in character.
- 12. Characteristics of a Good Sample 8. Actual information provider • A sample should be as to provide actual information required for the study or research.
- 13. Characteristics of a Good Sample 9. Practical • A sample should be practical. • The sample should be simple i.e. it should be capable of being understood and followed in the fieldwork.
