Questions With Verified Answers 2026
Data Point - correct-answer-Observation/record of (perhaps multiple)
measurements for a single member of a population or data set. In the standard
tabular format, a row of data.
Decision - correct-answer-Choice of action.
Decision Point - correct-answer-Place in a simulation where there is a branch (or
decision to be made or observed).
Decision Tree - correct-answer-Tree-based method for decision-making. After
branching to split the data, each subset is analyzed with its own decision model
(or just has its own decision applied).

Deep Learning - correct-answer-Neural network-type model with many hidden
layers.
Descriptive Analytics - correct-answer-Loosely speaking, the use of analytics to
explain or describe what has happened.
Design of Experiments - correct-answer-Choosing a set of tests to be made to find
the effect of input variables on an outcome.
Deterministic Simulation - correct-answer-Simulation with no
randomness/uncertainty, so results are the same each run
,3|Page
Detrending - correct-answer-Removal of trend, such as a change in the mean over
time, from time-series data.
Diagnostics odds ratio - correct-answer-Ratio of the odds that a data point in a
certain category is correctly classified by a model, to the odds that a data point
not in that category is incorrectly classified by the model; equal to (TP/FN) /
(FP/TN) = (TN*TP) / (FN*FP)
Diet Problem - correct-answer-Classical optimization model for finding the least-
costly set of foods that meets all dietary requirements.
Differencing - correct-answer-Using the difference of successive values in time
series data, rather than the values themselves. Sometimes nonstationary data will
have stationary differences.

Dimension - correct-answer-A feature of the data points (for example, height or
credit score). (Note that there is also a mathematical definition for this word.)
Discrete-event simulation - correct-answer-A simulation that models a system
that changes when specific events occur.
Distance - correct-answer-How far it is between two points -- but there are
different ways to measure it (see Minkowski distance).
Distribution-fitting - correct-answer-Determining whether a set of data seems to
follow a certain probability distribution, or determining which of several
distributions the data is close to.
Double exponential smoothing - correct-answer-Two-parameter exponential
smoothing technique that incorporates trend.
