Pada materi ini, kita akan belajar untuk membuat data yang semula tidak bersih menjadi data yang lebih berkualitas dan siap untuk diolah lebih lanjut. Beberapa proses pembersihan data (data cleansing) yang akan kita pelajari di antaranya menangani missing values, duplikasi, dan format/tipe data yang salah. Setelah memahami materi ini, kita dapat memastikan bahwa data yang kita olah memiliki kualitas yang baik.
