Analyse de l'application TRTT: Statistics & .sav Data pour le 23 octobre

TRTT is a complete statistical analysis tool that runs entirely on your device. Open, edit and save .sav and .zsav data files (the format used by IBM SPSS Statistics), import CSV and Excel workbooks, run the analyses you know, and share publication-ready output. FREE — WITH EVERY FEATURE Every analysis, every chart, the data editor and the syntax editor are free to use with datasets of up to 100 cases. Nothing is held back behind a feature list. Open a larger file and TRTT offers you a choice: load its first 100 cases and carry on for free, or unlock full dataset size. TRTT PRO (IN-APP PURCHASE) TRTT Pro is an optional in-app purchase and it unlocks one thing: dataset size. With it you work on files of any length, from a 500-case survey to a full register extract. Choose a weekly or a monthly subscription, or buy the lifetime unlock once and keep it (lifetime includes Family Sharing). Everything else is already in the free version, and stays there.
