Ucr collects data from crimes which are reported to

This preview shows page 7 - 8 out of 8 pages.

UCR collects data from crimes which are reported to the agencies of police and are then submitted. These data is collected from all the agencies which enforce law across the country. The main strength of UCR is that it is very easy to see the crime trends from the statistics which are currently reported. The weaknesses of UCR is that a flaw of report can occur in the cases where reporting fails. Further, anyone who is searching for evidence of a crime rate can base his/her opinion on the news media. Lastly, UCR does not go into detail of a specific event. NCVS on the other side cannot measure all criminal activity because not all crimes are reported to law enforcement. Mostly, researchers interview household members in a nationally representative sample. The data is collected regarding characteristics and frequency of criminal victimization by a variety of crimes, many of which may not have been reported to law enforcement. The strength of NVCS is that it provides estimates of the total amount of annual crimes, not only those reported to police. Additionally, it helps understand why crimes are not reported and the criminal event influences. The weakness is that there will be over-reporting due to victims' misinterpretation of events and underreporting due to the embarrassment of reporting crime to interviewers, fear of getting in trouble, or forgetting an incident. 10.

Also, which method, in your opinion, is least effective and why.

Techniques of observation are: Notes: They are commonly used and easiest method of recording observations. It includes organizing some shorthand symbols beforehand so that recording your observations does not impede your ability to observe. Video recorder or tape recorder Videoing or tape recording: this technique has the positive effect of allowing somebody to re-analyze your observations but these methods have the negative effect of increasing how intrusive you are as an observer and will often not be practical or even allowed in places such as a court room. Still camera: For the snapshot method of observation an ordinary camera can sometimes be used. In most situations, a single photo does not show enough detail, because the people being observed are usually facing different directions. Self-observation: this means getting respondents to observe themselves. This mainly involves the use of diaries, which respondents are meant to fill in whenever they do a certain activity, such as watching TV. Paper and clipboard: the observer will require the two items in order to record on one side of the line when he/she sees the observer doing an activity. The other side will be ticked if the observer is not doing the activity. The most effective method of recording observations is taking notes. This is because it is the easiest method and will store information for a long time for future reference. The least effective method is the use of self-observation. This is because most respondents aren’t motivated to fill in the diary every single time they do the activity of interest. Often they mean to fill in the diary, but forget. Sometimes they deliberately lie. Thus, the method gives inaccurate results.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
