6. Discrete or Continuous
Types of DATA
DATA
Qualitative
Quantitative
Ordinal
Nominal
Interval
Ratio
Can be recorded
(cost, weight, etc.)
Can be counted
(people, trees, etc.)
Discrete
Discrete or Continuous
Can be assigned
(ownership status:
1-owner, 2-rent)
Can be arranged in order
And difference between
number has meaning:
(IQ)
Can be arranged in order
(excellent, very good,
good)
Discrete: Data that contains only integers
As Interval but there is
Definite zero point
(no. of defects)
Continuous: Data that contains any value over a particular range

7. DATA
Pieces of information gathered by individuals and/or organizations to gain knowledge
Population
Sample
Set of all possible information that is interest
Portion of the population from which information is gathered
Data may be difficult to obtain
Data may be expensive to collect
WHY ?

8. WHO ? WHY ? Scientists Chemists Engineers Decision makers Economists

Inform the public
Provide comparisons
Explain outcomes
Predict for future
Establish a relationship
Estimate unknown quantity

18. Requirements to ABET EC 2000
Design Reliability

19. Definitions Reliability Design Reliability
How long will the system operate before failure?
Design Reliability
The level of reliability inherent in the system as designed or manufactured

20. Design Reliability Level of Reliability affects by: Weakness in design
Flaws in materials
Defects from manufacturing process
Maintenance errors
Improper operation

21. What is required? Design requirements to minimize the human errors:
Safety instructions
Maintenance rules
Operation manual
Apply standards

22. Requirements to ABET EC 2000
Risk Assessment

23. Definitions Risk Assessment
Formal and systematic analysis to identify and quantify probabilities and consequences for personnel, environment, production etc of all failures of equipment/installation/facility

24. What is required? Requirements to minimize the risk:
Recommendation report
Use available tags
