Statistics is generally termed as a branch of applied mathematics concerned with the collection of quantitative data and the use of probability theory to estimate population parameters. Descriptive statistics (distribution, summary statistics), run charts, and probability (distributions) are used for developing process control charts and developing process capability indices. A technical staff should have expert knowledge to manipulate and estimate the probability of an event occurring.
This course is designed to help students to understand the fundamentals of random variables, probability distribution and decision making and also to analyze statistical data graphically using frequency distributions and cumulating frequency distributions.
After completing this course, students will possess a basic understanding of descriptive and inferential statistics, and their practical use in making decisions in business and industry.
