Urgent help | Information Systems homework help

1.  We take a sample of adults and measure their heights. If we record the gender of each person, we can calculate the average height and the variance of the height, separately, for men and women. Suppose, however, that this information was not recorded. Would it be possible to still obtain this information? Explain. 

2.  In CLIQUE, the threshold used to find cluster density remains constant,

even as the number of dimensions increases. This is a potential problem

since density drops as dimensionality increases; i.e., to find clusters in higher

dimensions the threshold has to be set at a level that may well result in the

merging of low-dimensional clusters. Comment on whether you feel this is

truly a problem and, if so, how you might modify CLIQUE to address this

problem.
