The objective of this course is to impart students at the PhD level with a holistic view of the fundamentals of experimental designs, analysis tools and techniques, interpretation and applications. Upon completion of this course, the students will know (i)basic statistics including ANOVA and regression, (ii)experimental designs such as RCBD, BIBD, Latin Square, factorial and fractional factorial designs , (iii)application of statistical models in analysing experimental data , (iv) RSM to optimize response of interest from an experiment,and (v) robust design of process and product.

Final grades will be assessed based on three components:(i) internal assessment (IA) consisting of home assignments, term projects and attendance (20%), mid-term examination (30%), and end - term examination (50%).(ii) It is mandatory to submit home assignments (HA) and term projects (TP) within due dates. Failing of which leads to non - evaluation of mid - term or end-term answer scripts.(iii) Late submission will lead to reduction of marks in IA. If the assignment marks (e.g.,HA or TP) is x, the marks to be awarded will be x-d, where d is the delay in number of days. Zero marks will be awarded for d >= x
Home assignments & term project:

Instructions for Tutorials , assignment & term project :
(i) The tutorials and assignment will have to be programmed by the students either in R - studio or in SAS . (ii) The data & instructions for the tutorials and assignment shall be provided be forehand. The tutorial class might also be converted to home assignments. (iii) The problem statement & data sets of the capstone project have to be given by the students by the end of first module. The project should comprise of the applications of the DOE taught throughout the semester in the area of quality or service .
