Empirical data. Advantages and Disadvantages of Observation Method: For collecting information regarding various things surrounding us, the most common method is to observe and study the things around us.The various processes related to things should also be studied and observed. Each approach has advantages and disadvantages. There isn't one ideal way to gather information. There is so much to think of but there are tools . The procedural elements of content analysis as described by Berelson19 (1952) include subject selection, the development of inclusion criteria, classification, and analysis of results. In some situations, they may be the only available option for a researcher besides doing nothing. The Top Five Go-To Requirements Elicitation Methods. Additionally, there are numerous examples of the use of historical data to examine criminal offenders from Albinis (1971)14 study tracing the origins of the Mafia to Sicily to Clarkes (1982)15 study of assassins and their motivations. Recent examples of research involving content analysis include the examination of criminal justice pioneer importance as measured by existing biography length,20 crime drama portrayals of prime time justice,21 last words of Death Row inmates and news coverage of executions in Texas,22 portrayals of gay and lesbian police officer depictions in the core cop film genre,23 and constructions of crime and justice as portrayed in American comic books.24 While such research can be found in mainstream criminal justice and criminology journals, journals devoted to media topics, such as the Journal of Criminal Justice and Popular Culture, and Crime, Media, Culture: An International Journal, have been established to focus primarily on such issues and research methodologies. They could, however, look back to letters, diaries, and other written documents to better understand what was being thought and felt at the time. What are the costs of making respondents prone to participate in each of the data collection methods? Certain variables may not have been included in the original data collection, limiting the questions that can be answered by analyzing the existing data. 34 Bornstein, B. H. (1999). Like any assessment technique there are some advantages and disadvantages to using key informants: ADVANTAGES DISADVANTAGES Opportunity to establish rapport/trust and get an insiders * view Other community members who are not being used as key informants may become jealous and resent being left out Can provide in-depth information about causes .
