This course “Probability and Statistics” is a 8-credit course on Stochastic Processes and Multivariate Analysis. IGNOU undergraduate course “Probability and Statistics” (MTE-11) is a prerequisite for this course. The course consists of eight blocks. The first four blocks of this course are presented to bridge the gap between the theory and applications of stochastic processes. The proofs of theorems which are either too involved or do not help in understanding concepts are omitted. The theorems are supported with applications. In the last four blocks, multivariate analysis has been presented which includes the practical component. This deals with the observation and analysis of two or more than two statistical variables at a time. The practical assignments session-wise are given at the end of corresponding units.
