For the second session, Mr. Kumar further elaborated on the methods of data analysis available for a researcher and its scope, giving practical examples. He also explained the different ways of data tabulation, discussed the time series graphs, descriptive /summary statistics and introduced them to T-test and hypothesis testing using Gretl software.
