Respond to this discussion question with reference. Statistics helps represent a common method of information presentation to help us understand what information we are getting from the data. Statistics is a mathematical discipline of data collection by studying the collected data, analyzing, interpreting, presenting, and finely organizing the data. It is important for persons working in health care to understand statistical concepts, and for nurses to apply evidence-based patient practice care it's important to be able to interpret findings. Statistics help with everything from disease prevention to and effectiveness of new treatments. Historically statistics was developed in the 19th century as a study of population and economies and later as a mathematical tool for analyzing such numbers. The two statistical terms are regression analysis and hypothesis testing. Regression analysis used in healthcare is an important method that is used to determine the relationship between several factors and disease outcomes or identify relevant prognostic factors of diseases. Regression is about how one variable affects the other, I think of how age may affect how we perform simple activities of daily living ADLs. Hypotheses testing is a method of statistical inference used to decide whether the data sufficiently supports a particular hypothesis, an example of hypothesis testing in healthcare would be to evaluate the effects of a drug controlling hypertension. The data could examine blood pressure as the outcome variable. The blood pressure of an individual is related to a variety of factors to keep it constant over a period of time.
