GNU PSPP yog ib qho kev pabcuam rau kev txheeb xyuas cov ntaub ntawv pov thawj. Nws yog dawb raws li nyob rau hauv kev ywj pheej hloov rau qhov kev pab cuam SPSS, thiab zoo nkaus li zoo ib yam li nws nrog ob peb qhov kev zam. Qhov tseem ceeb tshaj plaws ntawm cov kev zam no yog, tias tsis muaj "lub sij hawm foob pob"; koj daim ntawv PSPP yuav tsis "tawg" lossis txhob txwm tso tseg ua haujlwm yav tom ntej. Tsis muaj qhov txwv tsis pub muaj tus lej ntawm cov xwm txheej lossis qhov hloov pauv uas koj tuaj yeem siv. Tsis muaj pob khoom ntxiv los yuav thiaj li tau txais cov haujlwm "advanced"; tag nrho cov kev ua haujlwm uas PSPP tam sim no txhawb nqa yog nyob rau hauv cov pob tseem ceeb.

PSPP yog daim ntawv thov ruaj khov thiab txhim khu kev qha. Nws tuaj yeem ua cov ntaub ntawv txheeb cais, T-tests, anova, linear thiab logistic regression, ntsuas kev koom ua ke, kev txheeb xyuas pawg, kev ntseeg tau thiab kev tsom xam, tsis yog parametric kuaj thiab ntau dua. Nws lub backend yog tsim los ua nws cov kev txheeb xyuas sai li sai tau, tsis hais qhov loj ntawm cov ntaub ntawv nkag. Koj tuaj yeem siv PSPP nrog nws cov graphical interface lossis cov lus txib ntau dua.
