Statistics Concept

• The mathematics of the collection, organization,
  and interpretation of numerical data, especially
  the analysis of population characteristics by
  inference from sampling.
• Statisticians collect and analyze data, then
  calculate results using a specific design. They
  draw conclusions and make decisions in the face
  of uncertainty.

Bio-Statistics Concept

• The tools of statistics are employed in many
  fields business, education, psychology,
  agriculture, economics, etc.
• When the data analyzed are derived from the
  biological science and medicine, and the term
  used is biostatistics.

What Why is Statistics

• Statistics - science of data
• - study of uncertainty
• Biostatistics data from Medicine, Biological
  sciences (business, education, psychology,
  agriculture, economics...)
• Modern society
• - Reading, Writing
• - Statistical thinking to make the strongest
  possible conclusions from limited amounts of
  data.

7
Bio-Statistics Study Requirement

• Collecting data on subsets of the population
  (samples) can give valid information about the
  whole population.
• Knowing what has happened in the past can help
  answer questions about the present and future.
• Knowledge helps plan future tests, determines
  resource allocation, and improves quality.
• Study the safety of nuclear power plants
• Evaluate the environmental impact of pollution
• Determine the effectiveness of new drugs
• Estimate the unemployment rate
• Analyze consumer demand for products
• Plan and analyze agricultural experiments

What Can I Do With A Degree in Statistics

• Business and Industry Manufacturing -Build
  products and deliver services that satisfy
  consumers and increase the corporations profit
  margin. Engineering -Make a consistent product,
  detect problems, minimize waste, and predict
  product life in electronics, chemicals,
  aerospace, pollution control, construction, and
  other industries.
• Statistical Computing- Work in software design
  and development, testing, quality assurance,
  technical support, education, marketing, and
  sales to develop code that is both user-friendly
  and sufficiently complex

10
Health and Medicine

• Epidemiology-Work on calculating cancer incidence
  rates, monitor disease outbreaks, and monitor
  changes in health-related behaviors such as
  smoking and physical activity.
• Public Health- Prevent disease, prolong life, and
  promote health through organized community
  efforts, including sanitation, hygiene education,
  diagnoses, and preventative treatment
• Pharmacology-Work in drug discovery, development,
  approval, and marketing, to ensure the validity
  and accuracy of findings at all stages of the
  process.
• Genetics-Label possible indicators of genetic
  abnormalities, such as birth defects and early
  aging, or breed desirable characteristics in
  plant offspring

Learning and Research

• Education-Teach students, assess teacher
  effectiveness, or develop statistical models to
  represent student learning.
• Science Writing Journalism-Work with mass
  media, universities, and corporations to produce
  news briefs, articles, news releases, and other
  reports
• Government-Work in regulations for stock trading,
  pollution, and drug approvals, or testify in
  court proceedings, congressional hearings, and
  lobbying arguments
• Survey Methods-Collect data in the social
  sciences, education, law, forestry, agriculture,
  biology, medicine, business, and e-commerce, and
  for the government

14
Social Statistics and Natural Resources

• Law-Analyze data in court cases, including DNA
  evidence, salary discrepancies, discrimination
  law suits, and disease clusters.
• Consulting-Work on a temporary basis on a variety
  of projects including quality improvement,
  pharmaceuticals, ecology, and engineering.
• Agriculture-Study chemical pesticides,
  hydrogeology, veterinary sciences, genetics, and
  crop management in order to ensure optimal yield.
• Ecology-Address questions about the earths
  natural environment, including animal
  populations, agricultural protections, and
  fertilizer and pesticide safety.

Examples of BIOStatistics

• Where do Biostatisticians work
• 1. Academic fields
• 2. Government (e.g. FDA)
• 3. Non-profit organizations
• 4. Pharmaceutical companies or Contracted
• Research Organizations (Local CRO PPD,
• Chiltern, Quintiles)

Typical Activity of a Biostatistician 1. Sample
size requirement 2. Analysis plan at design
stage 3. Randomization 4. Sampling design 5.
Statistical Analysis Descriptive and
inferential statistics analysis

I became involved with statistics because
mathematics did not provide the avenue to cross
into other areas of science and continue to learn
about topics that interested me. I have stayed in
statistics because of the diversity that it
offers and because of the rational approach it
provides to seek solutions to problems. Dan

Typical Job duty of Biostatistician

• Duty of Biostatistician
• Write/review Statistical Analysis Plan (SAP).
• Write/review statistical section of protocol
  including sample size calculation, develop
  randomization schedule, mock up table
  shells/listing shells, provide specifications to
  programmers.
• Quality control the table from SAS programmer,
  and review listings.
• Validate deliverables.

23
How Do I Become A Statistician or
Biostatistician?

• By pursuing degree courses or Certificate/Short
  term courses conducted by various institutes.
• Short term courses along with job or any other
  degrees courses.
• Short term courses enhance the technical
  capabilities raise the job prospects.
• Institutes providing short terms courses are many
  but the best curriculum I found in Indian
  Biosciences Research Institute www.ibri.org.in

24
Skills Required and Opportunities

• Quantitative Skills-Statistics, Mathematics,
  Science
• Problem Solving Skills-Analysis, Teamwork
• Communication Skills-Verbal, Written
• Computer Programming Languages
• Foundation in Field of Application
• Diversity -Pure Research, Interdisciplinary Teams
• Advancement-Experience, education, and
  communication skills lead to professional
  advancement
• Versatility-Challenging and Exciting Fields of
  Application

25
Why Biologists, Health And Medical Experts,
Paramedical Professionals Refer Statistics?

• It is primarily because of nature of measurement
  which is linked to their daily jobs.
• Anatomy experts most often measure height,
  weight, length, circumference, width, breadth of
  organs of human and other organisms.
• Physiologists do the same as anatomists.
• Quite a significant number of assessment
  techniques are employed by biochemistry and
  microbiology experts.
• Pathologists have their own assessment
  techniques.
• Counting occurrences in terms of numbers, and
  frequency calculations are frequently required by
  health professionals
