1 Importance Of Statistical Analysis In Criminal Justice Name AMU CMRJ300 D003 01/21/16 It is true that different researchers use different types of research methods in carrying out their researches. One of those methods is the statistical analysis method. This research method develops a special methodology of research and processing of materials. It includes many steps which will lead to almost ultimate report (Walker & Maddan, 2012). It begins with mass statistical observations whereby the researcher is obliged to sometimes visit or make use of questionnaires sent evenly to collect the required data. It also includes grouping the information collected and getting the average values and indexes. The researcher can as well make a balance of graphics where he or she makes use of graphs to analyze data and other methods of statistical data analysis. The most effective way to learn statistics is through the conceptual approach whose concepts are to simply the facts, then make the facts relevant through the use of real-life examples, which in this case will include giving a number of crimes and their responses then those facts are shared by many procedures and then related to one another to make comparisons. These comparisons help to make conclusions. Statistical analysis is useful in criminal justice because this is a sensitive area which needs reality and the steps used in this method leads to the ultimate truth (Vito, Blankenship, & Kunselman, 2008). It follows three common stages of work with statistical data namely: Data collection; Data collection is important as it provides a basis for statistical generalizations, for a formulation of conclusions. This is a mass scientific organized observation by means of which the primary information about separate facts of a studied phenomenon is received. This is where as discussed earlier the researcher uses the methods of data collection like questionnaires given at random to various people and are supposed to fill. The people are to write not according to their views and opinions but as to how the matter occurred. If it is a bank robbery, they should describe the incident on how and when it happened without comparing it with what had happened before. Before the researcher records information from questionnaires, he or she should compare what the majority has and not from only one source. A researcher can also make use of interviews to collect data primarily. This is where the researcher visits the area of incident and interviewing the people who could be present when the incident happened. This may be oral and is better as the researcher can draw conclusions easily. Notwithstanding the researcher may decide to use both methods of data collection to get the best general ideas, as comparisons will be many. The second stage is grouping and summary. Here, grouping will involve bringing the collected data together and arranging them according to the responses of various informants. The res.
