Sampling error refers to?
Sampling error occurs when the sampling protocol does not produce a representative sample. It may be that the sampling technique over represented a certain portion of the population, causing sample bias in the final study population.
What is probability sampling and non probability sampling?
In probability sampling,every item in the population has a known chance of being selected as a member.In non-probability sampling, the probability that any item in the population will be selected for a sample cannot be determined.
Sampling is a method of estimating population?
Sampling makes it possible to make assumptions about the larger population based on a small sample. This is beneficial in the study of population and demographics.
How many different samples of size 3 (with replacement) can be taken from a finite population of size 10?
When sampling with replacement from a finite population, each selection is independent. For a population of size 10, each of the 3 selections can be any of the 10 elements. Therefore, the total number of different samples of size 3 that can be taken is (10^3 = 1000).

What is a finite number of all objects selected from the population?
A finite number of all objects selected from a population refers to a specific, countable subset of the entire population. This selection can be achieved through various sampling methods, such as random sampling or stratified sampling. The key characteristic is that the number of selected objects is limited and predetermined, allowing for precise analysis or study of the chosen sample while still representing the broader population.

Why is sampling with replacement used?
Sampling with replacement is used when it is desirable for each item in the population to have an equal chance of being selected each time, and when it is acceptable for the same item to be selected multiple times in the sample. This method is commonly used in bootstrap resampling and in situations where the population is large and well-mixed.

What is population sampling?
Population sampling is the process in which a group of individuals are selected to represent a population for the purpose of statistical analysis. Population sampling allows the analyzers to learn about a population without studying every individual in it.
For a large target population what are the sampling methods use to select the exact population?
There is no sampling method that will select the exact population.
When you sample with replacement are the trials independent?
They are, if the sampling and replacement processes don't introduce any bias.
What is The process of selecting representative elements from a population?
The process of selecting representative elements from a population is called sampling. Sampling involves selecting a subset of individuals or items from a larger group in order to draw conclusions or make inferences about the entire population. Various sampling techniques, such as random sampling or stratified sampling, can be utilized to ensure that the selected elements accurately represent the population characteristics.
What are the important sampling methods Explain briefly?
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.
