Question $10$: Ten True$/$False questions. Please answer True or

False, and provide a one sentence justification of your choice.

The answer to each subquestion is a boolean, either True or False.

$($a$)$ Noise is not a problem with count data. Explain. $($b$)$ For any two sets of real values, such as two vectors of size n $0,$ the

correlation is a value between $-1$ and $1.$ Explain.

$($c$)$ For reducing the size of a daily time series, it would be better to sample

than aggregate since sampling is a simpler process. Explain.

d$)$ Noise and outliers are sometimes the same. Explain.

$($e$)$ If an object is an outlier, then it is noise.

$($f$)$ A binary attribute with values $0$ or $1$ is also an asymmetric binary

attribute.

$($g$)$ If vectors of counts have a cosine measure of $1,$ the objects are identical.

Explain.

$($h$)$ Discrete variables cannot be ratio.

$($i$)$ Quantitative variables are continuous.

$($j$)$ Converting ordinal variables to asymmetric binary variables does not

lose any information
