He explained the basic definition and concepts related to biostatistics and various areas where biostatistics has application. He said that practically there is no area where statistical thinking and application are not required. He explained when and where to use different statistical methods such as survival analysis, health economics and operational research, vital statistics, demography, epidemiological methods and many more. He concluded his talk by saying that there is no clinical evidence without statistical evidence. The session was made thought provoking by questions posed by the participants. This was followed by narration of answers by the speakers.
Second talk session was delivered by Dr Mario Vaz, Professor Physiology, St. Johns's Medical College, Bangalore, on topic "Problem Identification And Formulation of Research question/hypothesis/study design".

He emphasized on the topics like criteria for choosing the control, cohort design, its advantages and disadvantages, criteria to select cohort, baseline assessment, experimental or interventional study. He concluded the talk by giving the importance of qualitative research.
Next captivating session was delivered by Dr NC Jain, Director, Scientist G and Head ICMR, New Delhi, on topic " Importance of Introduction and Review of Literature in Developing Research/Thesis Proposal. He began his talk by focusing on research output of scientist. He gave an incredible insight of various resources related to research. Dr Jain explained the format of research proposal in a very simplified and easy way. He concluded by giving guidelines and keys for literature review.
Post lunch, session was addressed by Dr V Sreenivas, Professor Biostatistics, AIIMS Delhi, on topic "Concept of Sampling". He initiated his talk by giving introduction on concepts of sampling, that includes aims, objectives, population, sampling design, sampling frame, methods of sampling, stratified sampling.

He initiated his talk by putting some light on topics like benefits of planned data management, life cycle of data, ground rules for data collection and data management. He talked about the nature, type, objective of measurement, measurement errors, reliability and validity, biochemical assay. Dr Mario emphasized on ensuring the valid data collection, ICMR guidelines regarding record keeping and archiving and data reviewing prior to analysis. The lecture proved to be very informative for the participants.
DAY 2 10.02.2018
On the second day of workshop, the first session was addressed by Dr Atul Juneja, Scientist E ICMR, National Institute of Medical Statistics, on the topic "Testing of Hypothesis - Statistical Issues". Dr Atul explained statistical hypothesis, descriptive and inferential statistics and analysis approaches towards testing of hypothesis. He gave the concept of testing a hypothesis that includes two hypothesis i.e. Null and Alternative hypothesis, alternative hypothesis test statistics and rejection region. At the end of his presentation, Dr Atul explained statistical errors, p-value power and level of significance.
The second session went on by Dr Tulsi Adhikari, Scientist E, National Institute of Medical Statistics, ICMR, New Delhi, on the topic "Introduction of Descriptive Statistics". Dr Tulsi talked about descriptive statistics measures, measures of central tendency, measures of dispersion and variability which include range and standard deviation.
In addition to the above, Dr Tulsi continued by explaining the statistical terms like coefficient of variation, skewness, kurtosis, their types, normal distribution (symmetrical or asymmetrical) and explained the summarization of data by using descriptive statistics and graphs like bar charts, histograms, pie charts, line diagrams and seatter diagrams.
Post lunch session was addressed by Dr Atul Juneja on the topic " Sample Size Calculation". Dr Atul talked about causation, clinical and biological importance of sample size, components of sample size calculation that includes power and level of significance. He explained standard normal distribution curve in a simplified way.
The session was an interactive session between resource person and participants.
The post coffee session included the hands on training of descriptive statistics in SPSS software. This was a practical training session. Dr Tulsi Adhikari demonstrated the basic procedural steps to use the SPSS for calculating the components of descriptive statistics. This was an interactive session.
DAY 3 11.02.2018
The last day was dedicated to a practical training session.
Dr Tulsi Adhikari gave introduction to correlation and regression analysis and its application in health research.
Then there was hands on training of regression analysis using EPI info software.
