Memorize Translations Between Odds and Percentages
Edit 4/1/2024: I no longer use this deck. Since publishing this, I think I've gotten better at learning how to use Anki effectively — I endorse some better version of this deck, whereby you memorize translations between odds and percentages, but I don't endorse this deck.
Quickly translating between odds and percentages can be pretty helpful for intuitive forecasting. I made a flashcard deck to improve my translation skills; you can download the CSV file below, then import it to Anki, Quizlet, or whatever you use for flashcards.
