  • Hi Shimi, can you check if the new 'numeric category' field type is an integer or a real (e.g. by checking if the characters are aligned to the right)? If not, I know you did it but be sure that the two layers are in the same CRS (e.g. with ogrinfo or the QGIS browser). Commented Feb 10, 2016 at 13:58
  • It is aligned to the left. I now made a second column using toint() of the first column, and the new column is still aligned to the left in the attibutes table. However, the Basic Statistics analysis tool does not produce mean/std/etc for the first column and does produce them for the new column. Sadly, still I'm not getting the desired result. The max column is now actually added but it is filled with NULL. Commented Feb 10, 2016 at 14:22
  • Regarding the CRS: I checked with QGIS browser and they are exactly the same. Commented Feb 10, 2016 at 14:29
  • My first comment seems to be wrong. I don't know what happened but I can no longer re-produce what I did there. With the validated numeric category (produces basic statistics on the whole set) I'm getting just a NULL "COUNT" column, as described in the OP. Commented Feb 10, 2016 at 15:24
  • If I was you, I would start all the steps again, beginning by the field calculator and making sure that the 'Output field type' is set to 'Whole number (integer)'. Commented Feb 10, 2016 at 15:46
