Data: GEO-AT_hinded-osalus_2003-2012.xls


These data contain blank missing data cells which you should exclude (filter out). Unfortunately the blank cells are not on same rows for alla variables. So the blanks should be filtered out separately for each variable pair.
In the SDC you should select Non-spatial correlation, but other packages for statistical analysis should work as well.
