Assignment
1. Obtain one of the data sets available at the UCI Machine Learning Repository and apply as many of the different visualization techniques described in the chapter as possible. The bibliographic notes and book Web site provide pointers to visualization software.
2. Discuss the advantages and disadvantages of using sampling to reduce the number of data objects that need tobe displayed. Would simple random sampling(without replacement) be a good approach to sampling? Why or why not?
3. Describe one advantage and one disadvantage of a stem and leaf plot withrespect to a standard histogram.
4. Compare sepal length, sepal width, petal length, and petal width, using Figure3.12.
5. Comment on the use of a box plot to explore a data set with four attributes:age, weight, height, and income.
6. Give a possible explanation as to why most of the values of petal length andwidth fall in the buckets along the diagonal in Figure 3.9.
7. Simple line plots, such as that displayed in Figure 2.12 on page 56, whichshows two time series, can be used to effectively display high-dimensional data.For example, in Figure 2.12 it is easy to tell that the frequencies of the twotime series are different. What characteristic of time series allows the effectivevisualization of high-dimensional data?
8. Describe the types of situations that produce sparse or dense data cubes. Illustrate with examples other than those used in the book.
9. How might you extend the notion of multidimensional data analysis so that thetarget variable is a qualitative variable? In other words, what sorts of summarystatistics or data visualizations would be of interest
10. Discuss the differences between dimensionality reduction based on aggregationand dimensionality reduction based on techniques such as PCA and SVD
