That is probably the LABEL that is attached to the variable.
Try this example:
proc means data=sashelp.class ; var age; run; proc means data=sashelp.class ; var age; label age='age'; run;
You can either use a LABEL statement to remove the label. Or add the NOLABELS option to the PROC MEANS statement.
As to why someone would make a variable named SL with a label of 'Score SL Score' makes no sense. Or worse why anyone would make a variable named 'SL Score'n with an embedded space in the middle of the variable name and then also attach a label to it that did not add any extra information.
Are you sure the printout was not something like "SL_SCORE SL Score" ? That makes more sense because then the variable name is probably SL_SCORE and the label is "SL Score".
