Identify the sampling techniques used, and discuss potential sources of bias(if any).

Identify the sampling techniques used, and discuss potential sources of bias(if any). Explain.Using random digit dialing, researchers call 1400 people and ask what obstacles keep them from voting.

What type of sampling is used?

A.

Simple random sampling is used, since each number has an equal chance of being dialed, so all samples of 1400 phone numbers have an equal chance of being selected.

B.

Convenience sampling is used, since the 1400 phone numbers that are easiest to reach are selected.

C.

Cluster sampling is used, since the phone numbers are divided into groups, several groups are selected, and each number in those groups is called.

D.

Systematic sampling is used, since phone numbers are selected from a list using a fixed interval between phone numbers.

 

What potential sources of bias are present, if any? Select all that apply.

A.

Individuals may not be available when the researchers are calling. Those individuals that are available may not be representative of the population.

B.

The sample only consists of members of the population that are easy to get. These members may not be representative of the population.

C.

Telephone sampling only includes people who have telephones. People who own telephones may be older or wealthier onaverage, and may not be representative of the entire population.

D.

Individuals may refuse to participate in the sample. This may make the sample less representative of the population.

E.

There are no potential sources of bias.

 

The colors of candies such as M&M’s are carefully chosen to match consumer preferences.

The colors of candies such as M&M’s are carefully chosen to match consumer preferences. The color of an M&M drawn at random from a bag has a probability distribution determined by the proportions of colors among all M&M’s of that type.

(a)   Here is the distribution for plain M&M’s:

Color         Brown    Red   Yellow Green  Orange Blue

Probability     0.3       0.2       0.2       0.1       0.1       ?

What must be the probability of drawing a blue candy?

(b)   The probabilities for peanut M&M’s are a bit different. Here they are:

Color          Brown   Red   Yellow  Green OrangeBlue

Probability     0.2       0.2       0.2       0.1       0.1         ?

What is the probability that a peanut M&M chosen at random is blue?

(c)    What is the probability that a plain M&M is any of red, yellow, or orange? What is the probability that a peanut M&M has one of these colors?

Law Enforcement Stedman

 

1. Compare and contrast Strategic and Tactical Analysis and its application to street crimes such as robbery and property crimes such as burglary.  In your opinion is one more suited in addressing criminal behavior?

Strategic analysis involves the analysis over the long-term, whereas tactical analysis involves analysis in a more direct manner. Each has analysis scheme has their uses in addressing criminal behavior. To use an example with drug activity strategic analysis would be better suited to understanding who could be the future customers of drug dealers, where are possible locations that could facilitate such deals, and helping law-enforcement and community leaders come up with measures to combat drug sales. However, the tactical analysis would focus more on finding out where the current supply of drugs is coming in from, who the leader(s) is(are), and cracking down on local dealers. While there is overlap between the two, I believe that tactical analysis is the best when addressing criminal behavior, because of the more immediate results that it provides.

2.  What is CPTED?  Please elaborate on how CPTED may be an effective means to reduce a criminals Modus operandi?  Provide an example.  

CPTED is an acronym that stands for crime prevention through environmental design which is “The proper design and effective use of the built environment can lead to a reduction in the fear and incidence of crime, and an improvement in the quality of life” (Cozens, Saville, & Hillier, 2005). This means that CPTED is all of the passive defenses that the environment provides law-abiding citizens against criminally minded individuals. These defenses can be broken down into six different aspects that work together to create CPTED they are: territoriality, surveillance, access control, target hardening, image/maintenance, and active support (Cozens, Saville, & Hillier, 2005). All of these aspects work together to decrease crime in the area.

RESPONSE TO TERRENCE

 Socialization

     Leadership is motivating your subordinates to accomplish the goals and the mission of a department.  In order to accomplish this, leaders need to develop trust and a connection with their subordinates.  Getting to know your subordinates is important in that you are aware of their goals.  Are they on the job to provide for their families?  Are they looking to enhance their careers by joining a certain unit?   Are they just doing it because they are lost, and this job looked like something interesting to do while they figure themselves out?  Whatever their goals are, it should be important that their leader knows what those goals are. Another reason that it is a good policy to get to know your subordinates is to know if there is going to be any issues that may arise and to see if you can head that off.  If you go out with your guys/ gals and notice that one of them is hitting the bottle a bit harder than the, then you may have someone with a substance abuse problem.  If one of them is trying to start fights in the bar, then they may have an issue with violence that could translate to a problem on the job.

   You don’t want to get too friendly with your subordinates.  You don’t want to jeopardize the leader subordinate relationship and jeopardize your authority.  It’s hard to put the hammer down on someone that you just did a round of tequila shots with the night before.  There is a line that leaders can tow that keeps them as the boss, but not so far out of reach that subordinates feel as if they can’t talk to you.  It’s the old like that I learned when I became a leader.  Don’t take my kindness for weakness.   

   Finally, this is an important part of being a supervisor.  If you show that you care and that you can help them achieve those goals, then they will care about the work they give you.  They will put in an effort for someone who put time into them.  If there is a problem outside of work, they can head it off before it interferes with work. They may have access to resources that newer officers or employees may not be aware of yet.  If they see the boss putting some kind of effort into helping them, it can lead to a sense of loyalty.  If the boss really does his job right, that effort they put into their charge will get passed down.  The officer that was looked after, mentored and guided will then do the same for the next generation. 

    What could this mean for the organization?  It means more productivity for their officers.  Officers who feel as if they are not out there alone with their issues and that some one cares will be more focused on the job.  Officers who may be heading down the wrong path can be saved.  This can alleviate any embarrassment to the department plus the training costs to train a replacement for a fired employee.  This does not always work, however it is better than doing nothing.

Separation of powers is one of the most important principles in American government. Why is it important to have a neutral and nonbiased Supreme Court? 

Is it possible to have such a thing as a neutral and unbiased court? Explain your position.

Do we currently have such a Supreme Court? If we do offer an example, if not offer an example and explanation of how that is not an unbiased Court?

PLEASE EXPLAIN WHETHER YOU AGREE WITH MY CLASSMATE RESPONSE TO THE ABOVE QUESTION AND WHY? (A MININUM OF 125 WORDS) 

                                                                CLASSMATE’S POST

It is important to have a neutral and no bias Supreme Court, because of the chain of command. The Supreme Court is the last resort for fair decision in an appeal, if the judges are biased it’s no point in even moving forward or fighting for your rights of your rights being violated. The Supreme Court is for unconstitutional issue how can an appeal move forward if they are not biased. There are nine judges on the panel that would even it out if there in fact are some their vote may not count. 

I do believe there are bias courts. Reason for that is because, the constitution is interpreted differently. It is true that some are not bias but because of interpretation again it could be viewed as being bias and it actually is not. The courts have provided they are bias in so many different cases that with the evolution of technology, we can now see the bias courts from arrest to court system. From the political eye, if majority judges are of the same political party there would seem to be a bias from the opposing party of judges due to their views being different.
