Finding the Standard Deviation
Calculate the standard deviation.

IIIlI:.lIIJlCImDlIilUIImmlDl:S
The sample standard deviation for CPI is 2.27, for PPI is 5.8, and for
UR is 1.14.
Finding the Variance
Calculate the variance.
VAR

1: [5.17 33.64 1.30 ]
IIIlI:.lIIJlCImDlIilUIImmlDl:S
The sample variance for CPI is 5.17, for PPI is 33.64, and for UR is
1.3.
Paired-Sample Statistics
In this section you'll find the correlation and covariance of CPI and
PPI, then use a linear regression model to predict values of PPI from
values of CPI.
