We define statistics as a branch of mathematics as a means to analyze, understand what we observe and explain synopses, so as to create sense and meaning of our explanations and observations. Each day in life we come across information that originates in various forms. This is to means in order to put sense in this information; there is the necessity to use statistics. Though, due to its empirical applications and focus, statistics is typically regarded as a distinctive math’s sciences and not only a math’s branch (Chance et al, 2005) Therefore, in certain tasks a statistician use is less mathematical; for example, ensuring that collection of data is carried out in a way that yields effective deductions, reportage of results/coding statistical data in ways logical to the users. Statistics is recognized to advance the quality of data by shaping specific survey experiment designs and samples. It provides tools used to forecast and utilize data as well as the models for statistics. Also, it’s pertinent in many hypothetical fields that comprise the government, business, social and natural disciplines.
Descriptive or expressive statistics are exclusively used to designate the sample example under study. They are essentially used to describe the important features of a given data. They provide simple summaries concerning the measures and the samples. When utilized together with simple graphics study, they form the heart of practically each quantitative study of data. This means that descriptive statistics both made use of graphical and numerical summaries to explain a given data. Numerical summaries which can either measure the central tendency of a given set of data or which describe the spread of a given data. They use ...

...he data. It will be also paramount to investigate the results using evaluative means like the ANOVA test, which uses variance and makes sure that averages exists within every variable test group. There is also need to set a regression, which is a general statistical tool, which sees how variables are interconnected. Finally, there is the need to analyze the qualitative element of the analysis (Chance et al, 2005).

- ... The software that researchers use is often very expensive and has a steep learning curve. But, you don’t have to be a statistician or mathematical genius to use data. Descriptive statistics do not require one to have the statistical software or the statistical knowledge to describe the basic features of the data, but more often than not, descriptive statistics can be very powerful and persuasive when used appropriately. Defenders can use descriptive statistics to present quantitative descriptions of the data in a manageable form and it helps defenders to simplify large amounts of data numerically and/or graphically....

- Quality management frequently uses statistical methods to identify the existence of a quality problem and to analyze the root cause of the problem. Statistical methods require the collection of numerical data related to a process under investigation. The data can then be used to identify trends that can affect quality such as the rate of variance in the outcomes of a production process. The descriptive or inferential analysis of the statistical methods can also provide information about the most likely causes of the problem.... [tags: histogram, inferencial statistics, data]

- Several things can be done to the raw data in order to see what they can say about the hypotheses (Neuman, 2003). An inspection of the raw data can be done by using the descriptive statistics to find obvious coding errors. The minimum and maximum values for each variable must fall within the admissible range. Pairwise correlations depict that all relationships must be in the expected direction. Meanwhile, listwise deletion of missing values indicates that the data can be used for analysis. An outlier is an observation that is unusually small or large.... [tags: Data Analysis, Standard Deviation, Variance]

- Statistics should be interpreted with caution as they can be misleading; they can both lie and tell the truth. Whether or not people notice the importance of statistics, statistics are used by different cohorts of people from a farmer to an academician and a politician in their everyday life. For example, Cambodian famers produce an average of three tons or rice per hectare, connection about eighty per cent of Cambodian population is a farmer, and at least two million people support party A?. According to the University of Melbourne, statistics are about making conclusive estimates about the present or to predict the future (The University of Melbourne, 2009).... [tags: Statistics]

- Sampling is the raw resource which enables the quantitative researcher gain insight on the target population. In the past half-century, Haer & Becher (2012) note that surveys have become the ubiquitous data gathering devices serving many researchers purposes for assembling data in person or by mail. Nevertheless, the purpose of the survey is designed to gather valuable data, however, even more important is the design and in the way it is conducted ethically. Sampling strategies can be diverse depending on the resources and time available to a researcher.... [tags: target population, statistics]

- Statistics are necessary for scientific research because they allow the researchers to analyze empirical data needed to interpret the findings and draw conclusions based on the results of the research. According to Portney and Watkins (2009), all studies require a description of subjects and responses that are obtained through measuring central tendency, so all studies use descriptive statistics to present an appropriate use of statistical tests and the validity of data interpretation. Although descriptive statistics do not allow general conclusions and allow only limited interpretations, they are useful for understanding the study sample and establishing an appropriate framework for the fur...
