Basic Mathematics, combinatorics and calculus Knowledge.

Course Educational Objectives (CEO):

CEO 1To equip the students with a working knowledge of probability, statistics, and modeling in the presence of uncertainties.
CEO 2To understand the concept of hypothesis and significance tests
CEO 3To help the students to develop an intuition and an interest for random phenomena and to introduce both theoretical issues and applications that may be useful in real life.

Course Outcomes: At the end of the course, the students will be able to:

MCA105.1Distinguish between quantitative and categorical data
MCA105.2Apply different statistical measures  on data
MCA105.3Identify, formulate and solve problems
MCA105.4Classify different types of Probability and their fundamental applications
