Session 1: Prof. Arvind Pandey
Comparison of Mean: t-test, ANOVA
The Fourth day started with the lecture of Prof. Arvind Pandey, the Director of National Institute of Medical Statistics on ‘Comparison of Mean: t-Test ANOVA’.

The next session was in continuity of this in which Dr. Manoj Diwakar discussed ‘Statistical Analysis using SPSS’ through practical exercises on SPSS.
Session 2 & 3:Prof. Biswajit Das & Dr. Manoj K. Diwakar
Workshop on Statistical Analysis using SPSS
The second half of the day was kept for project work with the participants. The Director of CCMG, Prof. Biswajit Das allocated the work of preparing questionnaire for a survey on facebook usage. The participants were divided on seven groups based on seven different themes related to facebook usage. Before distributing the project work, Prof. Das deliberated on the question of why do we conduct research and what is it that we want to do with our research. Answering these questions he said that there are two purposes for carrying out a research: first is to legitimate and second is critical self reflection. He emphasized on the critical self reflection as it strengthen the epistemological knowledge. And for that interdisciplinary is essential instead of following tight compartmentalisation of disciplines. He also highlighted the fact that data cannot speak on its own. So no study is purely quantitative. The data would not suffice until it is weaved into qualitative analyses. Like many other resource persons, he also alluded to the issue of research question. He said that the day you know your research question half of your work is done. He also addressed the notion of time and space in terms of research. There are two ways of looking at the notion of time and space i.e. synchronic and diachronic where synchronic is the study of institutions used predominantly by Anthropologists and diachronic is the study of change over time in any society that falls into the disciplinary boundary of History. In addition to this he addressed the question of unit of analysis in any research. He referred to American sociologists, particularly Paul Lazarsfeld who is the pioneer of quantitative research. Lazarsfeld was the man who popularized quantitative research with the support of Ford Foundation that today quantitative research has become a dominant form in academic studies.
Session 4: Sumaandro Chattopadhyay
The last session of the day was on ‘Data visualization’. Mr. Sumandro Chattopadhyay, the Research Director at Centre for Internet and Society, Delhi spoke on how we see the data. He said data visualisation tell us how do we look at data. This is a newly emerging field in communication strategy. It involves presenting a substantial amount of structured data in a visual manner to communicate a specific insight. He enlightened the participants on how we are able to tell a story by data visualization. Data depends upon the context, questions and hypothetical answer. He shared some practical work-sheet with participants and described through different charts ad elucidated different types of data visualization like scatter plot, line chart, stacked bar chart, grouped chart, pie chart (circle in shape), doughnut chart, sunburst, tree map(rectangle shape), parallel sets and radar chart etc.
