–
One finger (the right finger) = A
–
Two fingers = B
–
Three fingers = C
–

Which of the following is untrue?
A.
Business intelligence and data mining are specific
applications of data science.
B.
Data science necessitates big data analytics.
C.
Machine learning is a specific application of
artificial intelligence.
D.
Data science requires domain knowledge, statistics,
computer programming, and database design.
Which of the following is not an
advantage of data mining?
A.
Most data mining methods are non-parametric
B.
It is data-driven and exploratory, and thus it reduces
confirmation bias
C.
It uses resampling-based ensemble methods rather
than counting on one single analysis
D.
Unlike the alpha level, the absolute cut-off of data
mining methods (e.g. AIC, BIC) is more objective.
What are the shortcomings of
conventional data?
A.
Sampling bias (e.g. WEIRD)
B.
In experimental setting the participants might behave
according to social desirability (e.g. the dictator game)
C.
In survey the respondents might not be able to recall
the exact information.
D.
All of the above
Which of the following statement is
untrue?
A.

Which of the following about data
mining is untrue?
A.
Data mining includes mining structured numeric data
and unstructured textual data
B.
Data mining utilizes machine learning
C.
Data mining necessitates pattern seeking
D.
Data mining is so named because the insight is buried
and thus it takes filtering and extraction to learn about
the data.
When the data size is extremely huge, it is
inefficient to transfer the data from the
database server to the analytical system. Which
of the following is NOT a solution?
A.
Hodoop
B.
MapReduce
C.
Distributed file system
D.
In-memory analytics
