A sample which is capable of providing reasonably accurate information...
Representative Sample:
A representative sample is a subset of a population that accurately reflects the characteristics and diversity of the entire population. It is a sample that is carefully selected to ensure that it is a true representation of the larger population. A representative sample is important because it allows researchers to make generalizations and inferences about the entire population based on the data collected from the sample.
Reasonably Accurate Information:
A representative sample is capable of providing reasonably accurate information about the population because it includes individuals or elements from all relevant subgroups or strata within the population. By ensuring that the sample is representative of the population, any patterns, trends, or characteristics observed within the sample can be considered reflective of the population as a whole.
Lower Cost and Shorter Time:
A representative sample is also advantageous because it allows researchers to obtain the necessary data at a lower cost and in a shorter time frame compared to collecting data from the entire population. Sampling a subset of the population is more efficient and cost-effective than attempting to survey or gather data from every single individual or element within the population.
Sample Unit, Sample Frame, and Random Sample:
- Sample Unit: A sample unit refers to the individual or element that is included in the sample. It can be a person, household, business, or any other unit of analysis.
- Sample Frame: A sample frame is a list or source from which the sample units are selected. It provides a comprehensive and complete listing of the population from which the sample can be drawn.
- Random Sample: A random sample is a sampling technique where each individual or element in the population has an equal chance of being included in the sample. It helps to eliminate bias and ensure that the sample is representative of the population.
Conclusion:
In summary, a representative sample is capable of providing reasonably accurate information about the population at a lower cost and shorter time because it includes individuals from all relevant subgroups within the population. It allows researchers to make generalizations about the population based on the data collected from the sample. Sample units are the individuals or elements included in the sample, a sample frame is the source from which the sample units are selected, and random sampling is a technique used to ensure the sample is representative.
