❗️ 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 🟠

• All questions about “Fasting Plasma Glucose” in this quiz refer to the measurement at the final visit: `fpg_of_final_visit_mmol_l`.
