IEE 380 FINAL STUDY GUIDE WITH SOLVED
QUESTIONS AND ANSWERS
◉ overcontrol.
Answer: having too much control over an experiment, as more
overcontrol there is more variability
◉ population.
Answer: a set of similar items or events which is of interest for some
question or experiment
◉ probability model.
Answer: 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.
Answer: Randomization refers to the practice of using chance
methods (random number tables, flipping a coin, etc.) to assign
subjects to treatments
, ◉ retrospective study.
Answer: a study using historical data, aka data collected in the past
for other purposes
◉ sample.
Answer: a data sample is a set of data collected and the world
selected from a statistical population by a defined procedure
◉ statistical inference.
Answer: Statistical inference is the process of using data analysis to
deduce properties of an underlying probability distribution
◉ statistical process control.
Answer: a method of quality control which employs statistical
methods to monitor and control a process
◉ tampering.
Answer: responding to variance to lower the variance will actually
make variability increase
◉ time series.
Answer: A time series is a series of data points indexed (or listed or
graphed) in time order
