Biostatistics In Biomedical Research

Introduction The topic that will be discussed is biometry/biostatistics. Biostatistics encompasses a lot of different fields put together. It is important in medicine, pharmacy, agricultural and fishery. It is useful because combines two subjects together(Biology and Mathematic), not only that, it is also used to improve different assortments of analytical methods. Biological Perspective of Biostatistics and It's Foundation Biostatistics is a theory and methodology for the acquisition and use of quantitative evidence in biomedical research (i.e. biomedical sciences.) Biostatisticians develop innovative designs and analytic methods targeted at increasing available information, improving the relevance and validity of statistical analyses, …show more content…

The result of the study was that use of HRT was stopped because of the negative events that took place to early into the study. But the important thing to look at here is the way statistics was used to quantify a decision. If the trial for HRT would have been cut short then we wouldn't have full information, but if the study would have continued then that would cause harm to a lot of people. This experiment is an important example because the decision was made on the statistical measure of probability that determined whether there was enough evidence that was gathered to make a decision to the stop the trial or keep it …show more content…

In that year an neonatal(relating to infants) intensive care center published the results of a trial comparing a standard treatment and a promising new extracorporeal membrane oxygenation treatment(ECMO) for newborn infants with severe respiratory failure.(Royal Statistical Science 1991, Volume 6) At the time this was considered a very promising project and that it would be a revolutionary discovery. Today it is a standard procedure. The problem at the time was that it was very difficult to conduct a trial for an experiment with obvious potential benefits. So what statisticians did was they came up with a specifically designed randomized scale where one infant was given the control therapy. This experiment and the one above shows how statistics plays an account in making public health decisions. The decisions that are made they play an importance when it comes to performing design, analysis and interpretation of data

They trusted the scientists so they thought they knew all they needed to know, but they didn’t know the most important. They didn’t know what would happen to their bodies after the experiment, they didn’t know that there would be possibilities of rectal tears or of impotence. (Kolata) If the biopsies came positive of prostate cancer, they would get a clean bed, 3 meals for a few days and free medicaid care and treatment. Also, being that they were positive for prostate cancer, a procedure would be performed where the prostate and possibly their testicles would be removed.

They also share commonalities in having the best research and clinical skills using scientific-based research to convey assessments and interventions. In order for clients to receive the best treatment we must use empirical science and evaluate treatment data to evaluate and make sure clients are receiving the best treatment possible for their individual needs. Furthermore, scientific approaches can ensure us that the interventions utilize should be the most effective. It is important that scientific practice provides us with the ability to acquire skills to evaluate and formulate hypothesis. The scientific-practitioner model ties into the BCBA guidelines as well.

1. What rationale do the author(s) give for conducting the study? The author that is conducting this research is testing the obedience of a subject when dealing with “stocking a victim” by use of a shock generator. There are thirty levels of shock that are generated varying from a slight shock to a severe shock.

Specifically the part of “and only 28% successfully ended the pregnancy.” Implies that of the women who have tried only 28% were successful. Meaning the other percent of the women's substances did not work which can leave everlasting damage to your body. Secondly, this also shows us how they could have made ever-lasting damage to their bodies. That may need medical treatment later.

First of all, the investigators should have respected the people they were going to conduct by obtaining an informed consent, letting the men decide if they want to be a participant after all. Second of all, medical researchers should not have lied to the people about how long this study was going to last. Third of all, both the risks and the benefits of it should have been stated to them so that the men could decide if this experiment is any beneficial to them or not. Lastly, the participants should have been randomly assigned to the control or experimental group without considering their race, class, and gender. Also, the medical researchers should not have the right to give the favored participants the helpful treatment rather than the riskier

Statistic is more accurate when it comes to show the level. For example, 1 bottle of soda might be “a few” for soda lovers, but it might be “too much” and unacceptable for the ones who want a healthy life or just hate the feeling of hiccups. Jacoby used statistics to support his argument, and let audiences get convinced after they get the numbers and start to feel the same way Jacoby feels. For example, when he discussed how jail is costly, he mentioned the price with the statistic. “Meanwhile, the price of keeping criminals in cages is appalling-a common estimate is 30,000 per inmate per year.”

The experiment uses basic research for the simple fact that it doesn’t do anything with the real world; you can’t conduct such an experiment in real life. Also, one of the definitions of basic research is that it aims to explain, predict, and describe fundamental bases of behavior, which is exactly what Watson wanted to do. Surely Watson and Rayner knew of the risks they were taking, conducting an experiment on such an infant. They knew it would have future, negative consequences, but still they went on with it just for the sake of proving a point of view. However, was proving a hypothesis worth hurting the psychological well-being of an innocent child, one that had absolutely no choice on what was conducted on him?

One aspect of public health research method that I learned is that measurement is central to quantitative research because it provides the fundamental connection between empirical observation and mathematical expression of quantitative relationships. I also learned that the goals and techniques associated with probability samples differ from those of nonprobability samples. If we want to get results that are valid for the whole study population, we should know how to draw a sample in such a way that it is representative of that population. But it is not necessarily that nonprobability samples are not representative of the population. It means that nonprobability samples cannot depend upon the rationale of probability

Official Statistics are used in research for many reasons but most commonly to detect trends and patterns in key areas such as crime and divorce rates. Statistics can provide the researcher with information but cannot explain the reason behind it, because of this official statistics are usually only the first step in the research

It’s a quantitative method that is specifically used in psychology researches and it examines whether two variables such as events, behaviuors, properties, and characteristics are casually related. In other words, it is a scientific and systematic approach to research, in which the researcher can manipulate and control the variables i,e an independent variable is manipulated and the dependent variable is measured and it could be called a true experiment. The main advantage of this method is that it allows us to determine and regulate cause and effect, and further it allows us to control the effects of extraneous variables. Experimental method involves some kind of measurement and a mathematical calculation is frequently involved.

Health statistics are important for knowing the health status of the whole population and its various segments and groups, as well as the trend in health status, the provision and distribution of healthcare services, and the impact of the provided services and programs. he success or failure of healthcare programs cannot be veriied without properly collected and interpreted health statistics. Proper allocation of resources also depends on health statistics. Researchers, presenters, and health care workers and students always need health statistics. However, it is not uncommon to ind a local article or presentation, which reports health statistics from all over the world, but fail to report local statistics from the Kingdom of Saudi Arabia (KSA).
