the sampled population includes all people whom are included in the sample, the targeted population is what the statistics practitioner is targeting or questioning

Which of these best describes why it is so important to have a representative sample?
To generalize results from the sample population to the target 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 are the disadvantages for random sampling?
its time consuming and expensive if its a large sample you need or a big target population
One weakness of self selected sample?
it is non-random and prone to bias unrepresentative of target population
What is the difference between stratified random sampling and cluster sampling?
Basically in a stratified sampling procedure, the population is first partitioned into disjoint classes (the strata) which together are exhaustive. Thus each population element should be within one and only one stratum. Then a simple random sample is taken from each stratum, the sampling effort may either be a proportional allocation (each simple random sample would contain an amount of variates from a stratum which is proportional to the size of that stratum) or according to optimal allocation, where the target is to have a final sample with the minimum variabilty possible. The main difference between stratified and cluster sampling is that in stratified sampling all the strata need to be sampled. In cluster sampling one proceeds by first selecting a number of clusters at random and then sampling each cluster or conduct a census of each cluster. But usually not all clusters would be included.

What question should a research consumer asked or Explore when evaluating sample size in a research report?
How representative is the sample relative to the target population.
What is the purpose of randomization in epidemiology studies?
ensure taht the sample for the study is representative of the target population
