## CORRELATE Command

Correlation is a measure of association between two
variables. A correlation coefficient can be calculated for ordinal, interval or
ratio-type data. This program can print descriptive statistics and a correlation
matrix for up to 88
variables.

The syntax of the command to run a correlation analysis
is:

CORRELATE <Variable list>

For example, to run a simple correlation of EDUCATION and
INCOME, you could type the command as:

CORRELATE EDUCATION INCOME

CORRELATE V1, V2

CO V1
V2 (CORRELATE can be
abbreviates as CO)

The correlation program can also correlate more than two
variables. For example, to print a correlation matrix of AGE, INCOME, ASSETS and
TEST-SCORE, you would type the command:

CORRELATE AGE, INCOME, ASSETS,
TEST-SCORE

The output would contain a correlation matrix of all
possible combinations of variable pairs. Several statistics can be printed for
each pair of variables. These are the correlation coefficient, number of valid
records, standard error of the estimate, t
statistic and probability of t.
