Purposive sampling involves selecting participants for a study based on some characteristic that you know they have. There is nothing random about their selection - it was done with intent. An advantage of this type of sampling is that it allows the researcher to quickly hone in on the target population. A disadvantage to this form of sampling is that researcher bias can creep in to influence results, if subjects are not chosen very carefully.
it is also used in political polling
The advantage of sampling in results is that it greatly simplifies results. If the sample is appropriately random, the results of the sampling will accurately represent the whole.

Advantages of cluster sampling include that it's inexpensive, fast, and simple. A disadvantage is that it is known to have a high sampling error.
Purposive sampling can allow the researcher to make generalizations about results. Purposive sampling also provides the researcher with many different sampling techniques.

They are the same size so you will know that it is always right. The disadvantage is you will have to depend on human accuracy in the project.
Propulsive Sampling Mean a sample which we can take randomly
Convenient sampling refers to using a sample group that is the easiest to gather. The advantage of this is that it is the easiest way to convene a test group. The down side is that the sample may not be representative of the population, so the results will be skewed.
it is a method used in order to recognize suspected population status in compression with their factors
Sampling techniques in research allow researchers to gather data efficiently and cost-effectively, providing a snapshot of a larger population. This can save time and resources compared to collecting data from an entire population. However, sampling techniques may introduce sampling bias, where certain groups are overrepresented or underrepresented in the sample, leading to results that may not accurately reflect the entire population. It is crucial for researchers to carefully select and implement sampling techniques to minimize bias and ensure the validity and generalizability of their findings.
Hi, 1.The main advantage of Systematic sampling over simple random sampling is its simplicity. It allows the researchers to add a degree of system or process into the random selection of subjects. 2.Another advantage of systematic random sampling over simple random sampling is the assurance that the population will be evenly sampled. Disadvantage The process of selection can interact with a hidden periodic trait within the population.
The advantage of sampling in results is that it greatly simplifies results. If the sample is appropriately random, the results of the sampling will accurately represent the whole.
