  9. 1. Banyak kelas : n = 80 2. Rentangan = data terbersar dikurangi data terkecil r = 99 – 32 = 67 3. Banyak kelas interval k = 1+3,3 log n (Sturges) k = 1 + 3,3 log 80 = 7,28 ≈ 7 4. Panjang kelas interval ≈ 10 Syarat : → 7 x 10 > 67 + 1 (benar) 5. Kelas interval i dapat dipilih: a. 30 - 39 b. 31 – 40 (paling baik) c. 32 - 41 k.i≥ r + 1
