Sample - CORRECT ANSWER-Any subset of the elements of a population
Population - CORRECT ANSWER-any finite ore infinite collection of individual units or objects
Statistical inference - CORRECT ANSWER-another name for 8 step scientific method
Retrospective Study - CORRECT ANSWER-Utilizes historical data that can sometimes identify
interesting phenomena
Observational Study - CORRECT ANSWER-A system is observed and data might be collected, but
changes are not made to the system
Designed Experiment - CORRECT ANSWER-an experiment in which the tests are planned in
advance and the plans usually incorporate statistical models
, Outliers - CORRECT ANSWER-One or more observations in a sample that are so far from the
main body of data that they give rise to the question that they may be from another population
Randomization - CORRECT ANSWER-Randomly assign treatments to experimental units or
conditions in an experiment. Used to remove bias.
Cause-and-effect - CORRECT ANSWER-A chart used to organize the various potential causes of a
problem. aka FishBone Diagram
Comparative Experiment - CORRECT ANSWER-an experiment in which the treatments that are
to be studied are included in the experiment. The data from the experiment are used to
evaluate the treatments.
Hypothesis Testing - CORRECT ANSWER-Any procedure used to test a statistical hypothesis
Hypothesis - CORRECT ANSWER-a statement about the parameters of a probability distribution
or a model, or a statement about the form of a probability distribution
Factorial Experiment - CORRECT ANSWER-A type of experimental design in which every level of
one factor is tested in combination with every level of another factor. in general, in a factorial
experiment, all possible combinations of factor levels are tested
Interaction - CORRECT ANSWER-In factorial experiments, two factors are said to interact if the
effect of one variable is different at different levels of the other variables. In general, when
variables operate independently of each other, they do not exhibit interaction.
Fractional Factorial Experiment - CORRECT ANSWER-A type of factorial experiment in which not
all possible treatment combinations are run. This is usually done to reduce the size of an
experiment with several factors.
