From 13th to 17th July 2020, ISBR Digital Academy organized a workshop on Analytics Using R for the students. The key objective of the workshop was to be able to use R effectively for Data Analytics. For the workshop, spread across 5 days, the topics were designed in such a way that even a person who is completely new to the R programming language was able to understand the basic concepts of R and then use it for basic analytical operations, giving a brief idea about the statistical aspect of the topics as well as practical application.
On day 1, An introduction was given on R language and basic concepts of R as a programming language were covered. A detailed overview of R programming language, including basic data types, variables, vectors, data frame, reading and writing files, probability, etc., were covered. Day 2 started off with the concept of understanding the datasets, how to clean the data so as to make it fit for analytical operations, descriptive statistics, visualization of the data using plots, etc were covered in detail. More advanced topics on understanding the relationships, associations, etc within the dataset were covered in Day 3 using different tests (parametric tests) such as t-tests, ANOVA, etc were covered in detail with the interpretation and visual representation of results as well as the statistical aspects. Non-Parametric tests were covered in detail in Day 4, with the interpretation and visual representation of results as well as the statistical aspects. On Day 5, an introduction to regression models was covered, having a detailed discussion on the Linear Regression model and Validation of the model, along with its statistical aspects as well as industrial applications.
All queries and questions were answered in the chatbox during the session itself. All errors were addressed and corrected via WhatsApp Group through screenshots from time to time. Quizzes were conducted on a daily basis right after the session to analyze the understanding level and effectiveness of the session. Individual guidance was given to participants who are completely new to the language. A number of sample datasets were made available to the participants and different sources to avail more sample datasets were also shared. A brief but detailed overview of the industrial application and practical aspects of the topics were provided. Few topics were also added in addition to the pre-planned topics, as per the request from the participants.
At the end of the 5-day workshop, a feedback form was collected from the students which suggested that all the participants found the workshop to be exciting, knowledgeable, and they looked forward to more of such events.
