When all the items in a population have an equal chance orocesss f being selected for a sample the process is called?
Random Sampling.
What is the difference between multiphase sampling and multistage sampling?
in multi-stage sampling the population is divided into a nonumber of units & in multi-phase sapling when certain items of information are collected from all the units in a sample and other itemsof usually more detailed information are collected from the subsample of the units composing the original sample.
Does cluster sampling assume that the population items are all alike?

How would you define the sampling universe and why you chose this sample definition?

What is the difference between sampling and random sampling?
Sampling involves selecting a subset of individuals or items from a larger population for study. Random sampling is a specific type of sampling method where each individual or item in the population has an equal chance of being selected. In random sampling, the selection of individuals is done purely by chance, reducing bias in the sample.

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 difference between Statistical Sampling and non-statistical sampling?
Statistical sampling is an objective approach using probability to make an inference about the population. The method will determine the sample size and the selection criteria of the sample. The reliability or confidence level of this type of sampling relates to the number of times per 100 the sample will represent the larger population. Non-statistical sampling relies on judgment to determine the sampling method,the sample size,and the selection items in the sample.
