Identify the correct sequence of the  Sampling Design Process from the given options:

A. Determine the Sample size

B. Select a sampling technique

C. Selection of sampling frame

D. Defining target population

Options:

Correct option is D

The process of designing a sample involves several crucial steps that need to be followed in a specific order to ensure the sample is representative and the research findings are reliable. 
The correct sequence of the Sampling Design Process:
1. D. Defining target population: Before selecting a sample, researchers must clearly define the target population, which is the entire group of individuals, objects, or events they want to study or generalize findings to. This definition should be precise and based on the research objectives.
2. C. Selection of sampling frame: Once the target population is defined, researchers need to develop a sampling frame. This is a list or representation of all the units in the target population from which the sample will be drawn. The sampling frame should be as comprehensive and accurate as possible to minimize sampling bias.
3. B. Select a sampling technique: After establishing the sampling frame, researchers choose an appropriate sampling technique. This involves deciding between probability (random) or non-probability (non-random) methods based on the research objectives, available resources, and the characteristics of the population.
4. A. Determine the Sample size: Finally, researchers determine the appropriate sample size. This involves calculating the number of individuals or items needed for the sample to achieve statistical validity, reliability, and precision while also considering practical constraints like time and cost. 
Therefore, the correct sequence is D, C, B, A.
