Q. 4 Write short notes on the following:

a) Essentials of a good sample

A good sample is a subset of the population that accurately represents the characteristics and diversity of the entire population. It is essential to ensure that the sample is chosen carefully to draw valid and reliable conclusions from the data. The following are some key essentials of a good sample:

1. Random Sampling: Random sampling ensures that every individual in the population has an equal chance of being included in the sample. This reduces bias and allows for generalization of the findings to the entire population.
2. Representativeness: The sample should be representative of the population in terms of key characteristics, such as age, gender, ethnicity, etc. This ensures that the sample accurately reflects the diversity present in the population.
3. Adequate Sample Size: The sample size should be large enough to provide sufficient statistical power to detect meaningful differences or relationships between variables.
4. Inclusion of Target Subgroups: If the research aims to study specific subgroups within the population, the sample should include an adequate representation of these subgroups.
5. Sampling Frame: A clear and well-defined sampling frame is essential to ensure that all individuals in the population have an equal chance of being selected in the sample.
6. Sampling Methodology: The sampling method (e.g., simple random sampling, stratified sampling, cluster sampling) should be appropriate for the research objectives and the characteristics of the population.
7. Bias Minimization: Steps should be taken to minimize any potential biases in the sampling process, such as non-response bias or selection bias.
8. Feasibility: The sample should be feasible to collect within the available time and resources.
