  2. RancanganAcakLengkap (Completely Randomize Design) Digunakanjikakondisi unit percobaanhomogen

  3. RAL • Rancangan Acak Lengkap (RAL)Diterapkan pada percobaan yang dilakukan pada lingkungan homogen (atau dapat dianggap homogen), Perlu dijelaskan disini bahwa yang disebut "lingkungan" adalah faktor-faktor lain diluar faktor yang sedang diteliti. Dalam percobaan RAL setiap unit percobaan di acak secara sempurna, tanpa dibatasi oleh kelompok dsb.

  4. Struktur Data

  5. RAL • Assumptions • Populations are normally distributed • Populations have equal variances • Samples are randomly and independently drawn
