Brief About Biostatistics Assignment Help
Biostatistics is about the study of application of statistics in the field of biology. This evaluates researches by collecting data, calculating and analyzing through various statistical tools that reveals the result and observation of the study conducted in medicinal, biological and agricultural fields. Sir Ronald A. Fischer is considered the ‘father of statistics’. Biostatistics refers to collecting, characterizing, presenting data and interpreting results that helps in controlling medical uncertainties. Medicinal biostatistics links medicine, health and statistics to reveal the outbreaks and occurrence of diseases trailed with preventive measures.While conducting any biological experiments it is very imperative to understand the principles of sampling and probability.Probability and sampling are the familiar terms in biostatistics: probability refers to the relative possibility or frequency that an event occurs or likely to occur and sampling implies to the selection of individual subsets from selected statistical population randomly.In simple words, large collection of people form population and part of a population represents ‘sample’.
The raw materials for an experiment in biostatistics is referred to as ‘data’ that might be a resultant of counts or measurements e.g., number of individuals or height of the patients in a given populace.The data is represented in three forms numerical, graphical or mathematical. There are many approaches to analyze data: numerical data – by forming frequency table; graphical data –line graph, bar chart, histogram, scatter chart, frequency curve, frequency polygon and pie charts; and mathematical data – measures of central tendency, measures of non-central tendency and measures of dispersion. The Measures of Central tendency includes Mean, Median &Mode: Mean is the average of the data, median represents the mid-line of a data (observation noted in the middle of the collected data), and mode is the most frequently occurred value in a data.The Measures of dispersion are Range, Variance, Standard deviation, Co-efficient of variance and Standard Error. Chi-square test, ANOVA, t-test, variance analysis, probability, correlation and regression are some of the calculative measures to observe and interpret the experimental outcomes. This forms a proof of support for the biological study. Surveying is another technique to obtain information about a particular event e.g., trait or disease.
Biostatisticians decipher the result and communicate it to others by following 3 simple steps to achieve proper result while conducting experiments: a) To monitor the purpose of an experiment or review prior to data collection, b) To scrutinize data using proper statistical procedures and c) To arrive and interpret the results to researchers and other decision makers.The applications of biostatistics is noted widely in epidemiology, nutritional and environmental research, clinical trials, ecological forecasting, sequence analysis of genetic materials, population genetics, microarrays, genomics and proteomics, breeding and hybridization studies, gene interactions, health service investigations and sampling analysis.
Biostatistics connects statistical inference to biological difficulties especially in clinical and pharmaceutical faculties. This records the medical history of any diseases, postulates devices for defining normal from abnormal and planning and evaluating different clinical studies and procedures.
