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.
