Assingment for law enforcement research design class

Qualitative, quantitative and mixed methods are methods used in research work to gather and collect data. Quantitative methods involve data collected in numerical amounts and have examples like surveys, structured interviews and performance test, where as qualitative methods involve data collected in the form of words or images. Includes semi-structured, unstructured, or open-ended data collection, content analysis, and comparing across Individuals. Examples of qualitative methods include; focus groups, observation and semi structured interviews. Mixed methods are a combination of both qualitative and quantitative methods hence providing the best results. The nine argument questions are also very important in qualitative, quantitative, and mixed methods of research (Marian, 2006).
The fundamental roles of research design components are an important aspect of every research design. They include; introduction which has : statement of problem, study purpose, theoretical perspective, research questions or hypothesis, definition of terms, delimitations and limitations, literature review which has type of design, sample population and participants, data collection instruments variables and materials, data analysis procedures, Anticipated ethical issues in the study, preliminary studies or plot tests, and significance of the study.
Hook and eye is an exercise designed to connect thoughts from sentence to sentence and from paragraph to paragraph. A good example of its use is in the article below.
Local Law Enforcement and Homeland Security
By Patrick Poole
Last month I had the pleasure of briefing a large group of local and state law enforcement officials on the Islamic extremist threat in their area. My interaction with these professionals reminded me that they are THE frontlinedefenders in the War on Terror and play an indispensable role in our Homeland Security.
Joining me in speaking at this event was my friend and occasionalAmerican Thinker contributor, LTC Joseph C. Myers.   What struck us both is how quickly they ” got it” when presented with the right amount of actionable information about what Islamic extremist groups were already operating in their communities. It was also impressive to see some of these agencies and departments who were doing very high-quality counterterror investigations even with limited personnel and financial resources. And in this case, those departments were working together to share that knowledge.
Having been raised in a police family (both my father and brother are retired from the job), Im familiar with the unique instincts developed by police officers day-by-day as they go about their beat. Recognizing something or someone out of place and a natural curiosity are necessary tools to being a good cop. However, one does not develop these skills and instincts sitting at a desk; they come from doing hundreds of traffic stops, shaking door knobs, talking to people and doing patrols in the community every day.
From the article it can be deduced that key words and terms which are important to the article have been highlighted in red and represent how thoughts connect and flow from sentence to sentence and from paragraph to paragraph. Like in this case the idea of terrorism being combated flows throughout the article where terms like Islamic extremists have been used several times to signify terror threats. In the third paragraph the term police has also been used several times to signify how the police are involved in fighting terrorism.
Hook and eye technique can be used to peruse through an article quickly and get the general idea just by citing the key words that have been repeated several times or those words that have been highlighted or underlined (Creswell, 2009).
