3. Objectives of biostatistics
The ultimate objective of biostatistics is to improve the health and quality
of life of individuals within a community or population. The main goals of
biostatistics are as follows:
 To diagnose the disease and treatment strategy with an estimation of its effects.
 To determine risk factors of disease
 Design, monitor, evaluate, interpret, and record the results of clinical studies.
 Measure, locate and explain the extent of disease.
 Develop statistical methods to give satisfactory answers to the questions that arise
from public health data.

4.  Application of biostatistics in the medical
field:
Biostatistics has numerous applications in science specifically in
the field of medicine. Its applications in medicines are briefly explained
as follows.
1. In physiology and anatomy
Biostatistics is used to find the ranges of normality in variables such as
weight and pulse rate etc in a population. It also helps to define the
correlation between two variables such as height and weight.
2. In pharmacology
• Biostatistics is used to compare the action of two different drugs or
two successive dosages of the same drug.
• It is also utilized to assess the relative potency of a new drug with
respect to standard drugs.

5. 3. In medicine
Biostatistics has multiple uses in medicines such as comparing the efficacy of a
particular drug by assessing the percentage cured, dead, or alive in experiment and
control groups.It is then compared and the difference is evaluated by applying
statistical techniques. statistical methods are also applied to find an association
between two attributes such as hypertension and diabetes.
4. In modern medicine
From analyzing data to determining the type and need of treatment during
clinical trials, Biostatistics has played an integral role in modern medicine.
Biostatistics helps to generate the facts and information on basis of statistical data
like heart disease is one of the leading causes of death in America. Such types of
outcomes are based on research-based statistical data and evaluations.

6. 5. In clinical medicine
Biostatistics is used as a tool in clinical medicine for the documentation of the
history of medical disease, designing, and planning of conduction of clinical trials,
assessing the merits and demerits of different procedures and methodologies.
6. In preventive medicine
Biostatistics is involved to introduce and promote health legislation. Moreover, it
helps to find out the actual reason underlying the disease and evaluate the success
rate of the health programs introduced in the community.

7. • Applications of biostatistics also vary from biomedical lab analysis to clinical
medicine to health promotion, to social and universal policies of health care to
medicine and the health sciences, involving clinical research, forensic medicine,
epidemiology, and public health.
7. In health care system :
 In the healthcare system, researchers used the scientific method to collect data
from samples of the human population. This data was used by healthcare
organizations to get knowledge about the variety of phenomena such as the
most prevailing diseases in a particular society or mortality rate due to any
particular disease.
 Moreover, biostatistics enables healthcare organizations to know about
consumer market characteristics such as gender, age, income,.
 Biostatistics is utilized to predict the type of services used by people and
determine the level of care affordable to them.

8. 8.Resource issuance
• Resource issuance is another important application of biostatistics in the
medical field. Valid Statistical information helps in resource allocation by
determining several key facts about resources and reducing the risk of
healthcare trade-offs, such as
 Which type of resources are utilized to produce goods and services?
 What is the most appropriate combination of goods and services that need
to produce?
 What type of community, it should be served?
9.Quality enhancer
• Quality improvement managers can measure feature results by building
standards of service excellence or by building benchmarks. Statistical data
collected over time displays the overall growth and ability to show more
growth of a healthcare organization or company.

9. 10. Product development
• Statistical analysis has a major role in the innovation and development of new
pharmaceutical products. Innovations and modifications in medicines start and end
with statistical analysis.
• In clinical trials of new drugs and treatments, data is collected and reported to
analyze product benefits in comparison to its risks. Statistics tend to influence the
pricing of products indirectly by defining consumer’s demand in the most appropriate
units.
11. Provide assessment
• Statistical data provides assessment to public and private health care workers and
organizations who are responsible to provide continuous care to a diverse population
and compare the existing services to community needs.
• A biostatistical analysis is a key factor in need assessment. Biostatistics plays a
significant role in technological and pharmaceutical companies in establishing the
product lines that meet the requirement of the community, they served.

10. 12. In the research field
• Biostatistics deals with human health and statistical data so it enables the
researchers to analyze data from medical experiments, design studies,
determine what data to collect, help illustrate the outcomes of the evaluations,
and participate in creating essays to report the results of the medicinal
investigation.
