Random Sampling
Instantaneous sampling is one method used for sampling a continuous time signal into discrete time signal. This method is called as ideal or impulse sampling. In this method, we multiply a impulse function with the continuous time signal to be sampled. The output is instantaneously sampled signal.
Sampling technique in research refers to the method used to select a subset of individuals or units from a larger population to gather data and make inferences about that population. Various techniques, such as random sampling, stratified sampling, and convenience sampling, can influence the representativeness and reliability of the research findings. The choice of sampling technique affects the validity of the results and the generalizability of the conclusions drawn from the study. Proper sampling ensures that the selected sample accurately reflects the characteristics of the overall population.
Suitable sampling techniques other than stratified sampling include simple random sampling, where each member of the population has an equal chance of being selected; systematic sampling, which involves selecting every nth individual from a list; and cluster sampling, where the population is divided into clusters, and entire clusters are randomly selected. Convenience sampling, though less rigorous, involves selecting individuals who are easily accessible. Each method has its own advantages and limitations, depending on the research goals and population characteristics.
This type of sampling method is used when data is gathered by sampling individuals from a certain group. For example, a researcher may ask for a sample of 200 students from an ivy league school as a sample for their survey.
Random Sampling
Stratified sampling is a sampling method in research where the population is divided into subgroups or strata based on certain characteristics. Samples are then selected from each stratum in proportion to the population, to ensure representation of all groups. This method helps to reduce sampling errors and improves the accuracy of the research findings.
You are correct; convenience sampling is not random sampling.
Sampling has multiple meanings depending on the domain of work:Statistics - Sampling is selecting a subset of population from within the population to estimate the characteristics of the whole population.There are two different types of Sampling Procedure;1. Probability2. Non ProbabilityProbability sampling methods ensures that there is an equal possibility for each individual in a population to get selected.Non Probability method targets specific individuals.
Answer is Quota sampling. Its one of the method of non-probability sampling.
because it is the simplest sampling technique which requires less time and cost.
Instantaneous sampling is one method used for sampling a continuous time signal into discrete time signal. This method is called as ideal or impulse sampling. In this method, we multiply a impulse function with the continuous time signal to be sampled. The output is instantaneously sampled signal.

cluster sampling
Important sampling methods include simple random sampling, stratified sampling, systematic sampling, and cluster sampling. Simple random sampling ensures every member of the population has an equal chance of selection, while stratified sampling divides the population into subgroups and samples from each to ensure representation. Systematic sampling involves selecting every nth member from a list, and cluster sampling involves dividing the population into clusters and randomly selecting entire clusters for study. Each method has its advantages and is chosen based on the research objectives and population characteristics.
