What sampling method does not require a frame?
Systematic sampling doesn't require a frame. This method takes in every data from a sample, rather than restricting it by any particular means.
Why is a frame necessary to obtain a simple random sample?
because it is the list that is used for assigning numbers to individual in the population.
Difference between sample and sampling frame?
A sample is a smaller group selected from a larger population. It may be to costly and time consuming to carry out the study on the whole population so the researchers choose a sample and often generalise results.A sample frame is the list of people from which a sample for the study are selected. It is only carried out on the target population that the researcher is interested in studying. For example finding data on just school children would not involve the the whole population only children in schools.

What is the size of a sample for a survey?
The population is every data point you intend to generalise the survey results to. The sample frame is those data points that you can pick from for the survey. The sample is which of these data points you actually survey, and the sample size is how many of those data points there are. For instance, if you have 700 students in a school, and you have access to 300 of them, and decide to give 30 of them a survey, the sample size is 30.
What is a sample of a population that has been selected using a pattern?
A sample of a population that has been selected using a pattern is when a researcher selects every 10th person from a list or sampling frame. For example, if a researcher wants to study the attitudes of employees in a large company, they may select every 10th employee from the company directory. This method ensures a systematic pattern in selecting the sample.
Define sampling design?
Sampling is a method of selecting experimental units from a population so that we can make decision about the population. Sampling design is a design, or a working plan, that specifies the population frame,sample size, sample selection, and estimation method in detail. Objective of the sampling design is to know the characteristic of the population.
