Which data collection method studies the relationship between variables where the data collected is in response to process input changes?
Designed Experiment
A design that uses every possible combination of factor levels to form a basic experiment with “k” different settings for the process
Factorial experiment
Where data is presently collected by a passive observer
Observational study
Consists of historical data, like board exam performances in the past year
Retrospective study
1-sample hypothesis test
A type of hypothesis test where the researcher compares 1 sample to a set/established criteria/data
2-sample hypothesis test
Where a researcher compares 2 samples simultaneously as they are both observed
the result of factors we can’t control in an experiment
Variability
What is a control chart?
A chart used to control quality by setting upper and lower control limits on a variable (plotted along y-axis) and keeping the points of that graph within those bounds
Mechanistic models are…?
… based on physical principles & theories and built from our underlying knowledge. Example: Ohm’s Law.
Empirical models are…?
… derived from empirical data, not theory, and rely much on observation and experimentation.
A mathematical representation of a random phenomenon.
Probability Model
Random Experiment (define)
Experiment where you have no control over the outcome. A dice roll is a good example, a coin flip is not (why tho).
What is a sample space?
It’s a set of all possible outcomes in an experiment.
What is an event?
A subset of a sample space.
The highest value of probability is?
1, which indicates certainty.
