What are three of the most important considerations related to sampling that would need to be addressed when working on a topic such as aggression with children. Explain how one might ensure that their sample represents this population of interest. Please use at least one journal reference.
What about sample sizes, missing data, and response rates? Can you please specify how might one ensure that their sample represents this population of interest? Are sample sizes, missing data, and response rates important to consider as they relate to sampling. If so,how?© BrainMass Inc. brainmass.com June 23, 2018, 5:58 pm ad1c9bdddf
First of all, you want to make sure that your sample is a good representation of the overall population you are interested in studying. The sample is the group of individuals actually participating in the study. It is necessary to ensure that your sample is a good representation of your population of interest, so that you can draw inferences and make valid and reliable conclusions.
In studying aggression, it can sometimes be difficult to observe the aggression directly. To obtain a solid sample from this population, it might be a good idea to obtain the data from student and teacher questionnaires, self-reports, peer feedback, etc. Obtaining rating scales, behavior reports or other types of assessment questionnaires is going to be very helpful for you. To conduct a study on human subjects, your proposal must pass what is called the IRB: Institutional Review Board. Most colleges and universities have their own IRBs, so check with your professor or Principal Investigator for more information. I am including the note on the IRB here, as it is one of the most important steps in obtaining the proper sample for your study.
One of the most important ways to assure your sample is representative of the population you are studying is to employ random sampling. This means that members from a specific population are all equally likely to be selected for the study. If the groups you studying are considered equivalent through randomization, then researchers are more likely to be able to reduce the chance of differences between the groups and to support cause and effect. Randomization of the sample is also important to support the internal validity of the study.
Another important aspect of sampling is to ...
This solution includes examples on sampling aggressive children, and what to look for in that population. It also includes information on sample sizes, missing data, and response rates that are important to consider as they relate to sampling. References are included as well.
