% Batang di Kiri, Daun di Kanan: Diagram Batang-Daun dengan TikZ
% Dokumen LaTeX utuh, siap dikompilasi (butuh paket tikz).
% Data: 30 nilai ulangan susulan kelas 8D, sudah diurutkan:
% 42, 47, 51, 55, 58, 60, 63, 64, 67, 69, 71, 72, 74, 75, 76, 78,
% 80, 81, 83, 84, 85, 87, 88, 90, 91, 93, 94, 96, 97, 99.
% Batang = puluhan, daun = satuan. Jarak antar daun 0,55 cm.
% Median = (76 + 78) / 2 = 77 (dua daun emas pada batang 7).
