Final Exam MIS 3300 Questions with CorrectAnswers
Decision tree Correct Answer-A data mining methodology where leaves
and nodes are generated to construct a predictive tree, whereby a data
miner can see the attributes which are most predictive of each possible
outcome in a target attribute is known as:
categorical, mixed Correct Answer-Decision trees can be a good choice
for a predictive model when the target attribute is in nature, and when
the data set is of types.
What the prediction is
how confident we can be in a prediction
how we arrived at the prediction Correct Answer-Decision trees can tell
us:
a measure of uncertainty (purity/impurity) used in classification
problems Correct Answer-In supervised data mining, the concept of
"Entropy" refers to:
Information Gain (IG) Correct Answer-A bank is interested in
classifying loan applications into one of three risk categories: low,
medium, and high. Each loan application provides information about key
attributes such as the applicant salary, credit rate, and age. We can
measure how informative an attribute is with respect to the target
attribute (i.e. Risk) by calculating:

Nominal Correct Answer-Discriminant Analysis requires a target
variable that belongs to which measurement classification?

larger than Correct Answer-Generally speaking, in supervised data
mining, the training dataset is ______ the testing dataset.
