Biostatistics and Statistics: An Emerging Career Opportunity Dr.Kumud Sarin (Ph.D,PDFGenetics,DU) Educational Consultant www.drkumudsarin.in www.ibri.org.in
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.
Business Physical Sciences Economics, Engineering, Marketing, Computer Science Health & Medicine Genetics, Clinical Trials, Epidemiology, Pharmacology Astronomy, Chemistry, Physics Areas where STATISTICS are used Environment Agriculture, Ecology, Forestry, Animal Populations Government Census, Law, National Defense
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.
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 corporation’s 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 userfriendly and sufficiently complex
Health and Medicine • Epidemiology-Work on calculating cancer incidence rates, monitor disease outbreaks, and monitor changes in healthrelated 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
Statistics And Biostatistics Encourage Investigators To Become thoughtful & independent problem solvers
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
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 earth’s 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 Mowrey
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.
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
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
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
Statistics in... Business & Industry :Research and Development - Experimental Design - Quality - Management Business Analysis -Market Research A Final Word... “I encourage young people who want to have interesting work which can make a positive difference to the quality of our lives is to consider statistics as a career.”
