BIOSTATISTICIANS
Making sense of all the data relating to living organisms and
transforming them into knowledge by using quantitative skills are
the work of biostatisticians.
"You can have data without information, but you cannot have
information without data." — Daniel Keys Moran

BIOSTATISTICS
TOOLS
Tools of the biostatistics help to find answers for pressing research questions
in biology, medicine, and public health. They may answer questions like,
How a new drug
works?
What
causes cancer?
What is the
reason for many
diseases?
How long could a
person survive
with a particular
disease?

BIOSTATISTICS
It is the development and application of
statistical models and theories of
inferential, probability and computing
and mathematics responsible for
interpreting the scientific data
generated in the health sciences.
Statistical methods encompass
designs of a wide range of biological
experiments.
Pharmaceutical studies and clinical trials, it
has developed in the directions of clinical
trial methodology.

Biostatisticians are in high
demand due to their various
responsibilities in scientific data.
Medical Research is to achieve
their ultimate goal of solving
problems in public health
by disentangling the received
data and make valid inferences.
It is the reason they are in
demand in government
agencies and legislative
offices.

BIOSTATISTICIANS - RESPONSIBILITIES
To determine the ways to utilize the vast
information and statistics obtained
through various sources.
Specialists of data evaluation, they
take complex and mathematical
findings of clinical trials and
research related data.

ROLES OF BIOSTATISTICS - CLINICAL RESEARCH
Reality is many profound doctors feel the need
biostatistics since in the time of their study it
was not in the medical study curriculum.
Doctors need to study biostatistics not only
for researchers but also to enhance their
reading capability of medical literature.
Evidence-based medicines as a
cornerstone for medical management,
biostatistics came into vital prevalence.

CLINICAL RESEARCH
All systematic researches carried out on human beings to generate data for
discovering or verifying the pharmacological, clinical or adverse effects with the
objective of determining efficacy and safety of the new drug are called clinical
researches.

Assess the relative benefits of

Establishing optimal treatment

devices.

ROLE OF BIOSTATISTICS - CLINICAL RESEARCH
METHODOLOGY
Evidence-based medicine are squarely depended on meta-
analysis.
Rock-solid evidence to help doctors in making decisions on
the best management options for patients.
Statistical methods will facilitate the understanding of the
randomized clinical research methods and results.
Biostatistics plays an important role in evidence-based medicine,
which is the base for doctors to recommend treatments for
patients now.
