Primer of Biostatistics - Term Paper Example During data analysis, quite often, either of descriptive statistics or inferential statistics methodologies is employed. Descriptive statistics (which unlike inferential statistics is not developed on the basis of probability theory) basically refers to the discipline of quantitatively describing the main features of a collection of data while inferential statistics on the other hand denotes the process of arriving at conclusions from data open to random or sampling variations (such as observational errors) (Graham, pg.40). Statistics is a wide field of study, probably one of the broadest disciplines available, with a plethora of applications too. The topic of ‘Fields of Application of Statistics’ is a rich topic in itself and one that sparks a lot of interest both to scholars and professions globally. Some of the sub-topics herein include actuarial science, astro-statistics, business analytics, chemo-metrics, demography, econometrics, environmental statistics, epidemiology, geo statistics, operations research, population ecology, statistical thermodynamics, and biostatistics and so on (Graham, pg.82). This paper deals with the biostatistics aspect of statistics. Biostatistics, commonly referred to as biometry, is the use of statistics in a wide range of topics in biology. Biostatistics deals with the design of biological experiments (such as in medicine, agriculture, pharmacy, fishery, etc), the collection, summarization and analysis of collected information from the experiments, followed by the interpretation of, and interference from, the results. Biostatistics is a combination of mathematics and reasoning, it considers how research questions are generated, studies are designed, data are collected and results interpreted. If the samples one takes are representative of the population of interest, they will provide good estimates concerning the overall population (Hubert).

People hit family members because they can Essay

People hit family members because they can - Essay Example Consider a couple named Chet and Margorie that had been married for ten years. Oftentimes Chet is a very domineering husband and many times has hit and abused his wife because he believed she did not do an adequate job of cleaning the house. While it’s easy to consider that Chet is just a violent person, one must also consider what would occur if Chet had a janitor that did not properly clean his office. In these regards, it seems clear that Chet would not attack the janitor. While Chet’s exact motivations are not easily discernable, Jacobson (1998) indicates that spousal abuse is oftentimes linked to dysfunctional relationship patterns and modes of communication within the household. Markowitz (2000) also indicates that spousal abuse more readily occurs, or is deemed ‘acceptable’ as compared to public violence, as the abuser is able to rely on the abused person’s emotional or financial dependence to ensure they will not receive punishment. In these regards, the abused person is often unable to leave or inform the authorities about the abuse because they rely on the abuser for their survival. While the earlier instance considers spousal abuse, family abuse also occurs in other forms. Consider the instance of David and Marie.
