Paper instructions:
Some of the engines we have studied this term include querying engines,
row and column manipulation engines, visualization engines and
statistical analysis engines. Our interfaces for querying were SQL and
the SAP Business Objects Analysis. For row and column, we had EXCEL, SQL
and SAP Business Objects Analysis. For visualization, we had EXCEL, SAP
Business Objects Analysis and R. For statistical analysis, we had EXCEL
and R.
This assignment examines SAP Predictive Analysis as an interface, and
asks you to match its visualization functionality with the engines and
interfaces we have studied already. The purpose is to get used to
thinking of data mining software in terms of concepts rather than
details. If you understand concepts, you will be able to deal with new
situations much more effectively than if you only memorize details.
1) To what engines does SAP Predictibe Analysis provde an interface? Explain.
2) Review the How to acquire data and do simple visualizations video
http://www.youtube.com/watch?v=nd4bnDguf1I. At time 1 minute and 5
seconds, the presenter moves the Category column to the Legend Color box
of the chart feeder. Describe the structure of an EXCEL pivot chart
that would produce the same color-coded bar chart. This type of coloring
is also called color brushing, and it is one of the most effective
techniques for exploratory visualizations.
3) Review the NCAA Final Four prediction video.
https://www.youtube.com/watch?v=ZZg2HsvfEaA At time 1 minute and 8
seconds, the presenter shows SAP Predictive Analysis interface for
merging two files. What previous interface that we studied could be used
for merging? Briefly explain the details of how you would do a merge
using the previous interface.
4) At time 3 minutes and 28 seconds of the NCAA video, the presenter
selects a set of bubbles and filters out all the bubbles outside the
box. https://www.youtube.com/watch?v=ZZg2HsvfEaA How would you do the
same kind of filtering in an EXCEL pivot chart. Hint: the solution is
extremely tedious and not nearly as easy as the SAP method.
5) How would you create a trellis chart in EXCEL? CLICK HERE FOR MORE ON THIS TOPIC
