For the results of the study conducted on the sample to be held true for the entire population, the sample should be a representative sample – that is, it should possess the same characteristics as the entire population, or as close to it as possible. A statistic is a characteristic that describes a sample; a parameter is a characteristic that describes a population.
The trend in the UK population is following an upward trend. From 61.8 million, the total population in the UK is reported to have reached 62.6 million in 2011 and again to increase up to 64.8 million in 2016. Other than live births, one of the main reasons why the UK population is continuously increasing is due to the upward trend of immigration.
Even within the same country, mortality can change due to differences in environmental or cultural factors. Also, a population’s age and gender composition can cause variations in mortality rates. Truly speaking from a Statisticians viewpoint it becomes extremely necessary to analyze mortality or disease in two locations by not just collecting a death rate data but to find on the impact of various factors or variables impacting the population in the two areas or at two scales which might be spatial factors such as the local natural or built environment or cultural factors that influence a rate.
Justification of the Research Question Cereal is one of the popular breakfast products in lot of countries of the world. Each day, consumers navigate through the cereal aisles in order to find the most nutritive, most savory products (Sifferlin).

Now design and analysis, the procedure is used to achieve trade studies in various dimensions by taking into account the properties of various variables.
On computing and comparing median for my town, Galion, this was $ 33,841 with that of Ohio, $45,395. It is clear that median is an effective measure as it divides the distribution into lower and upper halves. Given that an average of the data is likely to be affected and thus altered or influenced by extreme incomes in this case, it will be therefore not good to use mean as the measure of choice.

Calculated Risks by the cognitive scientist Gigerenzer has highlighted the fact that we are still living in the period of uncertainty, because we do not have the knowledge of statistical thinking. According to the author, risk and uncertainty is associated with every phase of our life, as the same can be seen while assessing damage in an accident or evaluating the medical screening procedure and results.
I am a person who has always possessed a natural aptitude towards mathematically handling things. Since childhood the game that I was best at was the stacking together of similar kinds of toys into separate bags and then labeling them with a general title.
It helps in designing strategies and planning business activities so that all business functions can be carried out in a most affective as well as efficient manner. A successful businessman must be a good decision maker and for taking decisions he would require some data which can only be gathered using statistical processes .This can better be understood by an example that a businessman while starting a business must know the purchasing power ,per capital income likes and dislikes of the public so that he plans his activities according to the requirements of the market .All such information can be collected by using statistical methods as it would not be possible to go and ask every country
In such a case, we will interview a few students selected randomly from the student population regarding their television watching patterns, then compare these values with their GPA scores using appropriate correlation tests. Generally, we expect a negative correlation between the two variables since GPA scores are seen to be low among students who spend more hours watching television and vice versa.
Higher education is becoming a distant dream for ordinary people in America now. American government is currently trying to implement globalization and liberalization policies. As part of these policies, the government is trying to stay away from spending much in the non-productive sectors.
Unemployment is as much of a social issue as it is a business issue. Unemployment reduces the purchasing power among consumers and, therefore, directly affects the profitability and at times the viability of many businesses.

Present global economic crisis not only has constrained the utilization of resources and but also hasstepped up the costs associated with the manufacturingthe products and offering the services to customers. This necessitates businesses to be more lean, agile and innovative structuring their decision making processes on facts based on data rather than on opinions and suggestions (Lyonnet, 1991).
In an effort to establish this, I formed a simple regression in excel to try and put the presumption verses factual nature of the issue to rest. I related the variable values of SAL and the variable values of the DJIA. In say a typical line graph, the values of these variables in my opinion would form a pattern when plotted on the graph that can be pinned down to a specific mathematical formula.

The points obtained on a scatter plot were connected using a best fit line such that the line passes through or close to the maximum number of points possible. The use of this technique allows the researcher to connect as many points as possible. The plotted points were then connected statistically using regressive techniques.
The present study is aimed at statistically analyzing the fact that what may be the specific reasons for the lessening of the birth weight may be related to the mother’s activities or health status. The study discusses the effects of ethnic background of the mother on the expected child along with the status of the health of the expectant mother.
According to the PMBOK, “a project is a temporary endeavour undertaken to provide a unique product or service” Nevell & Grashina (2004). This can be interpreted to mean that a project is quite distinct from day-to-day activities of an organisation in that it is not done on a regular basis.
Communication barriers are, however, external factors that may have intrinsic effects on a student to affect performance by either encouraging or discouraging the student. Font types and font sizes with which test questions are presented are identified to elicit different responses among students and readers in general.
Each of the corresponding values of X and Y designate a specific point on the graph and therefore when the points are all plotted they form scattered dots on the surface of the graph. This so formed pattern of plotted points scattered on the graph are attributed to the name of the graph, scatter plots.
Quantitative research confounds exist that influences research results against independent variables’ forces and therefore challenges implementation of quantitative research. History confound, maturation confound, and testing confound are examples of challenges to quantitative research.
Education providers have long been interested in determining the factors that influence student’s performance so they attain knowledge and skills essential to effectively contribute to community on a broader landscape (Kooi, 2008).
