Discrete Data
1.only certain values are possible 2. exist only for particular points in space 3. exist only for
particular points in time (Ex. Number of people, number of tripes to work, total population)
Continuous Data
values exist for all points in space or time, and/or all values are possible (Ex. height of a person,
distance to work, life expectancy of population)
Qualitative Data
are data that cannot be readily represented using numbers--may include opinions, sights,

interpretation and analysis
Quantitative Data
, are numerical measurements or representations
Precision
the "exactness" or the "specificity" of the measurement

the level of which measurements match the "actual" values--increasing levels of accuracy can
be achieved by better calibration, and a reduction in system-wide bias

can theoretically be specified with (practically) 100% certainty (eg gravity, solar radiation,

events are statistically independent if the outcome of one does not influence the outcome of the

OR the other happening can be calculated by adding the probabilities of each outcome
What does it mean for a classification system to be mutually exclusive and exhaustive? Provide
an example that illustrates both
