❗️ INTRODUCTION TO DATA QUIZZES ❗️
- On each quiz attempt, the data is reshuffled. So you need to reimport the data each time you attempt a data quiz! This is to prevent you from using the answer corrections from one quiz attempt in the next quiz attempt.
- If you retake the quiz, download the data again and view the first few rows using the
head()
function. Double check that the values in your data frame match the values shown in the quiz.
🟠 IMPORTANT NOTE ABOUT THIS QUIZ 🟠
- For fill-in-the-blank questions regarding the output of
tabyl()
, enter the values exactly as they appear in your output table, with the same number of decimal places, and the % sign if needed.
