Small data sets with only one or few variables can be listed simply as follows: 11 *DATA X: 17.3 -3.4 4.5 6.8 END 12 * 13 *DATA TEST:(X,Y,test1) 2,4,6 7,2,0 8,4,5 11,5,0 14 * 3,2,1 5,12,7 4,6,6 9,9,5 4,5,1 8,6,14 END 15 * Above two data sets X and TEST are written. Please, observe the colon ':' after the name of the data set. The X data has only one variable (X) with 4 observations. In the TEST data we have three variables (X,Y,test1) and 10 triplets of observations. END or an empty line terminates the list of values. These data can be used as any other in statistical operations. For example, CORR TEST computes the means, std.devs and correlations for the three variables of TEST. In more advanced applications other forms of Survo data representation should be preferred to. D = More information on data representation
