Across
- 4. a system by a set of variables and a set of equations that establish relationships between the variables
- 5. a variable for which the range of possible values identifies a collection of distinct cases in a problem
- 6. choosing a context, and then the specific aspects that interest each group
- 11. an approximate value close enough to the correct value
- 15. an experiment that is used to estimate the probability of a real-world event
