IEE 380 Exam Questions with Correct Answers
analytic study
Analytic studies are done to test specific hypotheses
cause and effect
Cause and effect refers to a relationship between two phenomena in which one phenomenon is
the reason behind the other
empirical model
Empirical modeling refers to any kind of modeling based on empirical observations rather than
on mathematically describable relationships of the system modeled.
Empirical: based on, concerned with, or verifiable by observation or experience rather than
theory or pure logic
hypothesis testing
a statement about a process behavior value compared to a claim about another process value,
data is gathered to support or refuse a claim
mechanistic model
built from our underlying knowledge of the basic physical mechanism that related several
variables
ex: ohms law
, current = V/R
I = E/R
observational study
a study where data is collected in the present by a passive observer
overcontrol
having too much control over an experiment, as more overcontrol there is more variability
population
a set of similar items or events which is of interest for some question or experiment
probability model
A probability model is a mathematical representation of a random phenomenon. It is defined by
its sample space, events within the sample space, and probabilities associated with each event.
The sample space S for a probability model is the set of all possible outcomes.
randomization
Randomization refers to the practice of using chance methods (random number tables, flipping a
coin, etc.) to assign subjects to treatments
retrospective study
a study using historical data, aka data collected in the past for other purposes
sample
