sangat penting sebelum seseorang melakukan pengolahan data. Skala pengukuran
pertama kali diperkenalkan oleh S.S. Steven. Namun, sering kali hal ini
dianggap remeh dan diabaikan. Pada dasarnya setiap <a href="http://paketartikelmurah.blogspot.com/">konten</a> <i>tools</i> (alat
bantu hitung) statistik tidak bisa digunakan begitu saja, ada persyaratan
(asumsi yang harus dipenuhi), misalnya : skala data, distribusi data,
independensi data, dan variabilitas data.<o:p></o:p></span></div>
