What type of sampling is used to estimate the percentage of defects?
random sampling
What are the disadvantages of random sampling?
used for a smaller population
Why do you use Stratified sampling?
They have used Stratified Sample. Design because stratified sample is a sampling technique in which the researcher divided the entire target population into different subgroups, or strata, and then randomly selects the final subjects proportionally from the different strata. This type of sampling is used when the researcher wants to highlight specific subgroups within the population. So in this Research this technique is used by the researcher.
What is the purpose of the sample proportion?
The sampling proportion may be used to scale up the results from a sample to that of the population. It is also used for designing stratified sampling.
When is it appropriate to use stratified random sampling?
it can be used when members of the population are heterogenous

What is the most commonly used sampling method?
The most commonly used sampling method is simple random sampling, where every individual in the population has an equal chance of being selected for the sample. It is preferred for its simplicity and unbiased nature in representing the population.
How probability sampling is used?
Probability sampling is used to select a sample from a population in such a way that every individual or element in the population has a known and non-zero chance of being selected. This method ensures that the sample is representative of the population, allowing for generalizations and statistical inferences to be made with greater validity and accuracy. Probability sampling techniques include simple random sampling, stratified sampling, cluster sampling, and systematic sampling.
What is Disribution used in estimating population variance?
The lognormal distribution, probably.
What is the purpose of the sample proportion?
The sampling proportion may be used to scale up the results from a sample to that of the population. It is also used for designing stratified sampling.
What is the sampling level?
The sampling level is the size or limit of a population used during a study. This level is used to determine if a particular standard or mandate is being met.
When is it appropriate to use stratified random sampling?
it can be used when members of the population are heterogenous
What is meant by sampling technique in research?
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.
What is primary sampling?
Primary sampling is a research method used by various companies for many different reasons. The primary sampling unit arises in sampling surveys where population elements are grouped, and those groups becomes units in the sample selection.
What are the sampling concepts?
Sampling concepts refer to the methods and principles used to select a subset of individuals or items from a larger population for analysis. Key concepts include sampling methods (such as random, stratified, and cluster sampling), sample size determination, and sampling bias. Understanding these concepts is essential for ensuring that the sample accurately represents the population, thereby enabling valid inferences and conclusions. Effective sampling enhances the reliability and validity of research findings.
