My View on Statistics Statistics, the all encompassing, universal method of scientifically verifying and studying individuals and their characteristics. The applications of Statistics in any field be it finance, psychology, computer science, ecology, etc. never ends. “Big Data” as some would call it defines the scientific driven decisions of modern companies (The Age of Big Data, Lohr). Statistics uses any type of data to describe a characteristic of many individuals in a population. This information goes into “Big Data” to evaluate the necessary actions to take on optimizing a desired result from the population. When it comes to divisive decisions that improve the world or fill someone’s pockets with boatloads of money, proper use of Statistics…
When used for its intended purpose, statistics can be the catalyst for decision making in the field of medicine, politics, science, economics, social science and nursing. Statistics can assist healthcare providers in their fight toward health promotion and disease prevention. It influences the discovery of new medicine and technology with the hope of one day eradicating many diseases. When statistics is misused, misinterpreted, and misrepresented the outcomes could be…
Kurtosis is a statistical measure used to describe the distribution of observed data around the mean. Descriptive statistics do not enable us to make conclusions beyond the data we have analysed or reach conclusions regarding any inference we might have made. Measures of variability are another important technique used in descriptive statistics. These measures define the methods of summarizing a group of data by describing how spread out the data is. To describe this spread, a number of…
Statistics review: Role of statistics in animal sciences Abstract This review throws the light on applications of statistics in animal sciences, and answering the question of how are statistics playing a vital role in veterinary field and biology .Also it presents different statistical methods that can be used in different studies. The basic statistical concepts should be known. The subject of statistics includes, design of a study that it will provide the biologist with the most information…
Multicollinearity Multicollinearity is one of the common problems in spatial regression analysis. Sometimes some or all of the explanatory variable are highly correlated in the sample data, which means that it is difficult to tell which of them is influencing the dependent variable (Barrow, 2009, p. 306). Hence, to check whether the independent variables are correlated with each other, a correlation matrix for the three indicators was measured using excel. The correlation matrix in table 2…
Discuss what descriptive statistics were used well in the Coffman article Descriptive statistics are is by researchers to describe, compare, and to characterize a relationship. (Polit, 2010) “Descriptive Statistics are used to present quantitative and qualitative descriptions in a manageable form” (Trochim, 2006). Coffman study on the the effects of tangible social support and depression on diabetes self efficacy in Hispanic older adults, demonstrated appropiate and good use of descriptive…
In our everyday life statistics are used in some form probably more than we realize. At home, you could be keeping a running average of your utility bills to see if differences appear. If you are looking at paying off your mortgage five years early, you will need to calculate the amount needed to accomplish this achievement. Some of us that may have purchased stocks will keep stats on the highs and lows of their investments to help determine a time to possibly sale the stock. The use of…
This portion of the study discussed the estimated results of each of the specifications. The objective is to have a clear understanding of the determinants of infant mortality. Stationarity Check: Regression of a non-stationary time-series variable may cause a spurious regression or non-sense regression (a symptom of spurious regression is that the R-square value is greater that Durbin-Watson test statistics) which is not desirable. After estimating the first regression, the R-square value is…
Non-mathematics majors doing statistics at university level in Cyprus: Factors behind their performance Nowadays, statistics education is ubiquitous at all education levels and across various disciplines (Scheaffer, 2002; Ben-Zvi and Garfield; 2010). Statistics courses have been incorporated into the curriculum programs in higher education institutions from the beginning of the 20th century (Verhoeven, 2009; Emmioğlu, 2011). A large proportion of university students are required to undertake…
