Can take a lot of time if the observer has to wait for a particular event to happen. Chapter 8: Putting It All Together: Understanding and Assessing Criminal Justice Research, 9. It involves checking and examining the existing data from reports, financial records, newspaper, website articles, Government publications, etc. The methods vary from traditional such as an interview, to modern ways and tools to gather data such as beautiful online surveys. Additionally, reactivity limits the generalizability of study findings as such findings can only be said to be true regarding subjects under the same conditions (i.e., those who are being observed at the time the behavior took place). In order to discuss these two points, I will focus on the two main characteristics that differentiate the FG from other techniques of information gathering in social research.

Sometimes obtaining data requires a phone call only, or establishing a contact within an agency. External sources of data: information gathered outside the researchers organization. This method involves extracting and analyzing data from existing documents. Information Retrieval is the science that tries to find appropriate tools for managing and retrieving information from large collections of data. for only $16.05 $11/page. Researchers should also take into consideration the original methods used to collect the data as well as the intentions of the original data collectors when using archival data. ADVANTAGES 1. Which technique is chosen by a researcher may depend on any number of factors, including the time available to conduct the study, the monetary or personal costs the study may entail, and the specific research question being examined. The following sections will examine in more detail the many types of unobtrusive methods utilized by researchers. Organizations can use a variety of quantitative data-gathering methods to track productivity. If a university administrator was interested in adding restrooms to campus and he needed to know where these additional restrooms would be most utilized, how could this be measured?

Advanced simulation setups are already utilized for criminal justice training, and their use could be extended for research purposes. As there were two researchers, or raters, analyzing the media content, an interrater reliability analysis was conducted to determine coding consistency between the raters. They could, however, look back to letters, diaries, and other written documents to better understand what was being thought and felt at the time. For example, if an agency or program wanted the original study to show favorable results, it could be that data was fudged in such a way that findings were as wanted, instead of as actually existed.
