Due 12/22Margin of error, sometimes called the confidence interval, is a term used in reporting results in forensic psychology research as well as in the world of polling and elections. For example, when reporting election results, you have probably heard the news media state something like the following: “John Doe has 51% of the vote with a 3-point margin of error.

Minus 3 percentage points

” This means that John Doe probably has 51% of the vote, but the results may not be entirely accurate. He could have any percentage between 48 and 54 (51 plus or minus 3 percentage points) of the vote, but only 95% of the time. The other 5% of the time he could have more than 54% or less than 48% of the vote.

Similarly, in a research study, the margin of error refers to how willing and/or likely you are to come to a false conclusion about the results of your research.To prepare for this Discussion:Review Chapter 6 in your course text, Research Methods for the Behavioral Sciences. Pay particular attention to the concept of margin of error and what it represents.

Using the Walden Library, select a forensic psychology research article of interest to you, and one that uses margin of error in reporting its results.Review the study keeping in mind the concept of margin of error and its implications in the study.Think about how and why the margin of error impacts the results of the study.

With these thoughts in mind:By Day 4Post by Day 4 a brief description of the research article you selected and a brief summation of the sections on methods and results. Explain how the margin of error is reported in the article, and how and why the margin of error impacts the results of the study.Stangor, C.

Due 12/26The accuracy of the results of research data is partially dependant on the sample that was used in the research study. How large the sample, its specific characteristics, and how it was selected, all play a significant role in how “good” the research results will be. Without appropriate sample size, characteristics, and selection, the results will be less than optimal.

Forensic psychology professionals

To this point, forensic psychology professionals often use existing databases from which to draw the data for their research; that is, they obtain their sample from these data bases. The problem with doing this is that the researcher does not have input into the sample represented in the data, such as how and from whom it was collected.

To prepare for this assignment:Review Chapter 6 in your course text, Research Methods for the Behavioral Sciences. Pay particular attention to when and where surveys are used in forensic research and the importance of representative sampling.Review the selected pages of Appendix B in your course text, Research Methods for the Behavioral Sciences.

 Pay close attention to the role of sample size in applying results to the general population.Using the Walden Library, select a forensic psychology research article that interests you. As you review it, focus on the section(s) discussing methods and results.Consider how the sample size, sample characteristics, and means of sample selection influenced the results of the study.

The assignment (1–3 pages):Briefly summarize the forensic psychology research article you selected, including the sections on methods and results, paying particular attention to sample size, characteristics, and means of selection.Explain how the sample size, sample characteristics, and sample selection influenced the results of the study and why.
