IEE 380 EXAM 1 QUESTIONS AND
ANSWERS (VERIFIED AND UPDATED)
Analytic study - ANS Analytic studies are done to test specific hypotheses
cause and effect - ANS Cause and effect refers to a relationship between two phenomena in
which one phenomenon is the reason behind the other
empirical model - ANS 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 - ANS 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 - ANS 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 - ANS a study where data is collected in the present by a passive
observer
overcontrol - ANS having too much control over an experiment, as more overcontrol there is
more variability
population - ANS a set of similar items or events which is of interest for some question or
experiment
probability model - ANS 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 - ANS Randomization refers to the practice of using chance methods (random
number tables, flipping a coin, etc.) to assign subjects to treatments
retrospective study - ANS a study using historical data, aka data collected in the past for other
purposes
sample - ANS a data sample is a set of data collected and the world selected from a statistical
population by a defined procedure
statistical inference - ANS Statistical inference is the process of using data analysis to deduce
properties of an underlying probability distribution
statistical process control - ANS a method of quality control which employs statistical
methods to monitor and control a process
tampering - ANS responding to variance to lower the variance will actually make variability
increase
