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).

- Understanding Business Research There are many different kinds of quantitative data collection instruments and sample methods accessible to researchers. The ones that I have chosen for the purpose of her paper are questionnaire, sampling and surveying. Each can be a worth to a researcher when completed with accurateness. Legitimacy is the degree to which implements measures what it is meanings to measure. Incorrect instruments can lead to invalid research at the end, which in turn can inspiration educational resolutions.... [tags: Mean, Arithmetic mean, Statistics, Question]

- ... 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....

What are the differences between descriptive and inferential statistics. Descriptive stats summarize data so the data can be comprehended. The researchers prepare a frequency distribution which shows the frequencies as descriptive statistics. Percentages, and averages are also descriptive statistics. Therefore, the descriptive statistics describe sets of data collected through observation.... [tags: Statistical significance, Statistics]

- ... Hence, we could rationally suppose that discrepancies are not uniform. Table 3 displays the yield of the ANOVA analysis as well as whether there is a statistically noteworthy difference amid the group means. The significance level is 0.597 (p = .60). The significance level is 0.597 (p = .60), which is above 0.05, therefore, there is not a statistically sizeable difference in the mean of visual acuity between the different periods of time spent viewing the digital device. This is helpful to recognize, however, this does not aid in identifying the specific groups that differed.... [tags: Statistical significance, Statistics, Effect size]

- 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]

Hence, after the EFA, this study will continue with the validity and reliability test. 4.6.6 Validity and Reliability Test Validity and reliability of the measurement are important in conducting a survey. Validity is associated with the accuracy of the measurement and reliability is dealing with the consistency of the measurement (Hair, 2011). According to Hair, validity of the measurement can be assessed by some criteria, such as face validity (content validity), construct validity (convergent and discriminant validity) and criterion validity (concurrent and predictive validity)....

- 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]
