Pre-requisite BMAT101L, BMAT101P Syllabus version
1.0
Course Objectives :
1. To provide students with a framework that will help them choose the appropriate
descriptive methods in various data analysis situations.
2. To analyze distributions and relationship of real-time data.
3. To apply estimation and testing methods to make inference and modelling
techniques for decision making.

Course Outcome :
At the end of the course the student should be able to:

1. Compute and interpret descriptive statistics using numerical and graphical


techniques.
2. Understand the basic concepts of random variables and find an appropriate
distribution for analyzing data specific to an experiment.
3. Apply statistical methods like correlation, regression analysis in analyzing,
interpreting experimental data.
4. Make appropriate decisions using statistical inference that is the central to
experimental research.
5. Use statistical methodology and tools in reliability engineering problems.
