I-GNU PSPP iwuhlelo lokuhlaziya izibalo zedatha eyisampula. Imahhala njengasekushintsheni kwenkululeko yohlelo lobunikazi be-SPSS, futhi ibonakala ifana nayo kakhulu ngaphandle kokuhlukile okumbalwa. Okubaluleke kakhulu kwalokhu okuhlukile, ukuthi awekho "amabhomu esikhathi"; ikhophi yakho ye-PSPP ngeke “iphelelwe yisikhathi” noma iyeke ngamabomu ukusebenza esikhathini esizayo. Futhi ayikho imikhawulo yokwenziwa enanini lamakesi noma okuguquguqukayo ongakusebenzisa. Awekho amaphakheji engeziwe ongawathenga ukuze uthole imisebenzi “ethuthukisiwe”; konke ukusebenza okusekelwe yi-PSPP okwamanje kusephaketheni eliyinhloko.

I-PSPP iyisicelo esizinzile nesithembekile. Ingenza izibalo ezichazayo, ukuhlola kwe-T, i-nova, ukuhlehla komugqa nokuhlelekayo, izilinganiso zokuhlobana, ukuhlaziya iqoqo, ukwethembeka nokuhlaziywa kwesici, ukuhlola okungezona ezepharamitha nokunye. I-backend yayo iklanyelwe ukwenza ukuhlaziya kwayo ngokushesha ngangokunokwenzeka, kungakhathaliseki ubukhulu bedatha yokufaka. Ungasebenzisa i-PSPP enesithombe esibonakalayo noma imiyalo ye-syntax evamile.

• Ukusekelwa kwamacala angaphezu kwebhiliyoni elingu-1.
• Ukusekela okuguquguqukayo okungaphezu kwebhiliyoni elingu-1.
• I-syntax namafayela edatha ahambisana nalawo e-SPSS.
• Inketho yetheminali noma isixhumi esibonakalayo somsebenzisi.
• Inketho yombhalo, umbhalo, pdf, i-opendocument noma amafomethi okukhiphayo we-html.
• Inter-operability nge I-Gnumeric, I-LibreOffice, I-OpenOffice.Org kanye nenye isofthiwe yamahhala.
• Ukungenisa okulula kwedatha kusuka kumaspredishithi, amafayela ombhalo nemithombo yolwazi.
• Amandla okuvula, ukuhlaziya nokuhlela amasethi edatha amabili noma ngaphezulu ngesikhathi esisodwa. Angabuye ahlanganiswe, ahlanganiswe noma ahlanganiswe.
• Ukusebenzelana komsebenzisi okusekela wonke amasethi ezinhlamvu ezivamile futhi okuhunyushelwe kuwo izilimi eziningi.
• Izinqubo zezibalo ezisheshayo, ngisho nasemasethi edatha amakhulu kakhulu.
• Azikho izimali zelayisensi.
• Asikho isikhathi sokuphelelwa yisikhathi.
• Akukho okungenasimilo "izivumelwano zamalayisense womsebenzisi wokugcina".
• A ikhombe ngokugcwele imaniwali yosebenzisayo.
• Inkululeko iqinisekisiwe; Ilayisensi ngaphansi kwe- GPLv3 noma kamuva.
• Ukuphatheka; Isebenza kumakhompuyutha amaningi ahlukene kanye nezinhlelo zokusebenza eziningi ezihlukene (i-GNU noma i-GNU/Linux izinkundla ezikhethwayo, kodwa sibe nemibiko eminingi yokuthi isebenza kahle nakwamanye amasistimu).
