On a ChatGPT Plus or higher plan, go to "Explore GPT" and search for "PsychStatsAII" in the "Search GPTs" field.
Attach the dataset you want to analyze in the chat input field, then enter and send instructions regarding the desired analysis method or data editing tasks you want the GPT to perform.
You can either type the prompt yourself or attach and send a sample prompt from the "Prompts" section of this site.
If the output is insufficient, send an additional message to the GPT, such as "Please perform multiple comparisons."
