Quantitative Method Of Investigation

What is a Hypothesis? There are many different methods of investigation, depending on what subject you are trying to gain further insight into but the most important first step is developing your hypothesis. Many different disciplines use similar investigation methods. One good example would be the law enforcement, methods of investigation that include interviews, observation, arrest records research, crime scene reconstruction, ballistic test, questioning of witnesses and suspects just to scratch the surface. Law enforcement investigation has many similarities to psychological investigation. They are both trying to answer questions that relate to “Critical -Thanking” such as the following examples of: 1) Always being skeptical of the

A very basic definition of the Quantitative approach involves the application of statistical analysis to law enforcement, psychological, and military research (Leedy & Ormrod, 2016). In simple terms this means being able to take the results of your research data that you have gathered and presenting it in a manner using a mathematical model. This can take the form of tables, graphs, or charts. The main thing to remember in the Quantitative method is it must be able to be assigned a numerical value. The Qualitative method differs from the Quantitative method in that it uses some quality or characteristic instead of a measureable values or quantity (Leedy & Ormrod, 2016). A good example of this would be law enforcement using interviews with a possible group of suspects in a crime to discover possible complexities surrounding the crime. As an few examples of research methodologies that have evolved as researchers developed a better understanding for human beings and how worldly phenomena affects us is the experimental method, observation method, and scientific method. Some of these methods are unique to what the researcher want to study and what kind of data they hope to gain and how they intend to apply what they learn. It is important to understand how these three methods are tied to the hypothesis for the problem they are trying to better
