  1. STATISTIKA Kurva Frekuensi Rosihan Asmara Fakultas Pertanian Unibraw rosihan@brawijaya.ac.id

  2. Kurva Frekuensi Contoh Tabel xxxDistribusi Frekuensi Nilai Penataran Statistik dari 126 Peserta

  3. Grafik Poligon

  4. Jika jumlah kelas mendekati tak hingga, luas kelas relatif kecil sekali, maka garis poligon tidak patah tetapi lengkung halus (smooth)

  5. Garis lengkung yang halus dinamakan kurva frekuensi

  6. Kurva frekuensi dibedakan • Kurva frekuensi simetris • Bila kurva dilipat tepat di tengah maka setengah lipatan akan menutup setengah lipatan lainnya • Kurva frekuensi asimetris • Bila kurva dilipat tepat di tengah maka setengah lipatan tidak akan menutup dengan tepat setengah lipatan lainnya

  7. Bentuk Kurva Simetris Kurva bel langsing (leptokurtik) Kurva bel normal (mesokurtik) Kurva bel gemuk (platikurtik) Kurva trapesium (rektangular) Kurva triangular Kurva bimodal

  8. Bentuk Kurva Asimetris (Kurva Juling) Kurva juling negatif Kurva juling positif Kurva J Kurva L Kurva U Kurva multimodal
