Drunk Driving Case Study Essay

1508 Words7 Pages

Introduction of the potential problem

The case study is on Drunk Driving. The data set contains number of deaths (in thousands) due to drunk driving, recorded from the year 1982 to 2001. So we can analyse the trend of whether the number of deaths is on a rise.
The analysis using the SPSS tries to analyse the changing pattern in number of deaths encountered.

Tool used for analysis: SPSS

SPSS is a statistics analysis tool developed by IBM Corporation. The software was released in 1968. It is generally used for data mining, text analytics and collaboration and deployment. SPSS stands for Statistical Package for the Social Sciences. It is used to do predictive analysis as well. It is widely used by professionals from social sciences, health research, survey, market research, data mining etc.
It is Windows based software and is essentially used for data entry, create graphs and to come up with …show more content…

Mean
Mean or average, in theory, is the sum of all the elements of a set divided by the number of elements in the set. Formula for mean:
Mean = Sum of all the set elements / Number of elements
The importance of mean lies in its ability to condense the whole dataset with a single value.

Median
Median is the middle value of a set. If a set consists of odd number of sets, the middle value is the median of the set, and if the set consists of an even number of sets, then the median is the average of the two middle values. The median may be used to separate a set of data into two parts. Median most accurately summaries the set, better than the mean.

Mode
The mode in a dataset is the value that is repeated most number of times in a data set. Like mean and median, mode is also used to summarize a set with a single piece of

If you have taken any kind of statistics course or have a middle school education then the definitions of mode, median, and mean should be familiar. With the median being the middle value in a set of data, mode being the most recurring variable, and mean being he average. In Steven Jay Gould’s essay, The Median isn’t the Message he describes his experience as he faced a cancer diagnosis early in his life. He was told that his median mortality was eight months. Naturally our mind is fixated on the value, eight months.

Kira Johnson Eng 111-11:00 Ms. Booms December 9, 2016 Drunk Driving: Proposal The solution to resolving drunk driving is to crack down on laws already set in place and monitor repeat offenders.

In standardized tests and tests in general, the mean is the average score derived from a group of scores. The mean is determined by adding up all the scores and dividing the sum by the number of scores added (Woolfolk, p. 632, 2013). The median, as the name implies, is the middle score. The median lies at the midpoint of a set of scores, with an equal number of scores distributed above it and below it. The mode is essentially the score that occurs the most often.

Inherent variability We take samples to form estimates of some characteristic of the population of interest. The variance of that estimate is proportional to the inherent variability of the population divided by the sample size: Var(p̂ )≈σ2n with p̂ denoting the parameter we are trying to estimate. This means that if the variability of the population is large, then we must take many samples. Conversely, a small population variance means we don't have to take as many

A histogram is a type of bar graph; its distinguishing feature is that it presents the information so that those accessing the information can see immediately the spread or distribution of scores within certain groups. The groups of scores are known as class intervals. A histogram would help people to see when a particular range within the group is scoring higher – for example in school tests. Histograms are a good way of seeing the general spread or distribution of scores as well as

Mean is the average, median is the middle piece, mode is the piece seen the most, range is the difference between the largest and smallest pieces, and standard deviation scores depend on the answers above. Normal curve is bell-shaped and describes the distribution. The next thing we learn about is the ways that someone’s culture and gender affects their behavior. Behaviors are very contrasting in different cultures.

Also, the distribution of the middle class varies by location and cost of living. The surrounding of where you live can impact the class you are in. For example if you live in an area with minorities, you are most likely in the middle class or lower class. The concept of the middle class goes beyond numbers it's very much a matter of feeling and a state of mind. For example black and older americans are most likely to be in the lower

The mean would be truthful about oneself no matter if it is good or bad just honest. This leads to being aware of ones flaws, the excess in this would be shy not willing to admit any flaws. The deficiency would be shamelessness, not embarrassed by anything and telling things way beyond what anyone else would have the need to know. The mean would be modesty, admitting one had faults but not overstating them. I like using this as a method to judge actions and interpreting them as good or bad.

This single number is simply the number of hits divided by the number of times at bat (reported to three significant digits). A batter who is hitting .333 is getting a hit one time in every three at bats. One batting .250 is hitting one time in four. The single number describes a large number of discrete events. Or, consider the scourge of many students, the Grade Point Average (GPA).

Two forms of variation: Continuous variation Characteristics showing continuous variation vary in a general way, with a broad range, and many intermediate values between the extremes. (www.biotopics.co.uk) As a matter of fact if you consider a large enough sample from population perhaps plotting frequency as a histogram or as a frequency polygon, you will find that most of the values are close to the average and extreme values are actually rather rare. High is an example of a continuous variable

Aristotle explains that the mean is extremes of excess and deficiency. Aristotle first explains this by comparing it to health and food. It was explained in medical terms that we ruin our health if we eat too little or too much. For instance, it is ruined by excess and deficiency. The mean is divided into three categories; extreme of deficiency (being a coward), mean (bravery or courage), and extreme of excess (rashness, reckless).
