Definition:
"A systematic, scientific, organized inquiry that provides information to `managerial decision makers"
1:Systematic: identify the problem and proceeds step by step
2:Scientific: The difference is verifiable, results of research be verifiable. There is the confidence of the decision.
Difference between confidence and decision
P (7080)=80% it interprets that I am 80% sure that the average marks of class in a particular subjects will between 70 and 80. This statement is precise and differentiable and testable.
P (0100)=100% it interprets that I am 100% sure that the marks of the students in a particular subject are between 0 and 100. This statement is not precise because it is obvious that the marks of students will in between 0 and 100
The level of confidence must not be very wide and it also must not be too short.
