  1. Rata-Rata Hitung dari data Tersusun Hamba Allah Achmad_tj@yahoo.com

  2. IRata-Rata Hitung dari data TersusunBerdasarkan Konsep Titik Tengah dan frekuensi x = x1 f1 + x2 f2 + ….. + x k f k f1 + f2 + ….. + f k x = ∑ xi fi = ∑ xi fi ∑ fi n Achmad_tj@yahoo.com

  3. Rata-Rata Hitung dari data TersusunBerdasarkan Konsep Rata-rata Dugaan& Interval x = M + (1/n) ∑ fi. di x = M + c/n ∑ fi. ui interval Achmad_tj@yahoo.com

  4. Median Data Tak Tersusun Data Yg Tersusun = Nilai Tengah Bagi Ganjil 2 Nilai Tengah Dibagi Dua Bagi Genap Me = Bb + c. s Me = B a - c. s’ = fM fM Achmad_tj@yahoo.com

  5. Quartile, Decile & Percentile Qi = Bb + c. s f qi Quartile Percentile Qi = B a - c. s1 f qi Pi = Bb + c. s f Pi Di = Bb + c. s f Di Decile Pi = Ba + c. s’ f Pi Di = Ba + c. s’ f Di Achmad_tj@yahoo.com

  6. Modus Data Tersusun Data Tak Tersusun Modus = B1 + ( d1 ) c Simple: Frekuensi d 1 + d 2 • Bimodal • Unimodal • Modus Banyak Achmad_tj@yahoo.com

  7. Simpangan Rata-Rata SR = (1/n) ∑ [ xi – x ] SR = (1/n) ∑ [ xi – x ] f i Achmad_tj@yahoo.com

  8. Simpangan Standar Data Tersusun Data Tak Tersusun S2=(1/n) ∑ (x i – x ) 2 S2=(1/n) ∑ (x i – x ) 2 f i Variance Variance (1/n) ∑ (x i – x ) 2 f i (1/n) ∑ (x i – x ) 2 Simpangan Baku S=√ Simpangan Baku √ ∑fi xi2 - { ∑fi xi} 2 ∑fi ui2 - { ∑fi ui} 2 √ √ C n n n n Achmad_tj@yahoo.com

  9. Pencaran Frekuensi Berbentuk J Berbentuk U Pencaran Merata Berbentuk J Terbalik Achmad_tj@yahoo.com

  10. Skewness (ukuran Asimetri) Md X Mo Mo = X =Md Sk = X – Mo s Rumus 1 X Md Mo Sk = 3 (X – Md) s Rumus 2 Koefisien skewness pearson Achmad_tj@yahoo.com

  11. Kurtosis (ukuran Keruncingan) Mesokurtis Leptokurtis σ4 = m 4= ( 1 )∑ (xi-x) 4 Data tk tersusun S 4 ns 4 Platykurtis σ4 = m 4= ( 1 )∑ (xi-x) 4 fi Data tersusun S 4 ns 4 Achmad_tj@yahoo.com
