  1. ANOVA SATU ARAH (Oneway Anova)

  2. MERUPAKAN PENGEMBANGAN DARI UJI t UNTUK DUA SAMPEL BEBAS • BERTUJUAN MENGETAHUI ADA TIDAKNYA PERBEDAAN NILAI RATA-RATA LEBIH DARI DUA PERLAKUAN

  3. ONEWAY ANOVA(ANOVA SATU ARAH) k ni x..2 TOTAL SS =  xij2 - ----- i=1 j=1 n k xi.2 x..2 BETWEEN SS =  ---- - ---- i=1 ni n WITHIN SS = TOTAL SS - BETWEEN SS

  4. TABEL ANOVA

  5. KRITERIA PENOLAKAN Ho : FSTAT > Fk-1 , n-k, 1- CONTOH : 4 KELOMPOK SUBYEK DIBERI 4 MACAM PERLAKUAN YANG BERBEDA DIUKUR DENYUT NADINYA

  6. Tabel Anova

  7. MULTIPLE COMPARISONS • UNTUK MENGETAHUI PASANGAN-PASANGAN KELOMPOK YANG BERBEDA • CARA : * LSD * HSD * SNK * DUNCAN * SCHEFFE * dll

  8. LSD (LEAST SIGNIFICANT DIFFERENCE) Ho : i = j H1 : ij RUMUS : LSD = t/2 , S ( 2 . MSE / n ) dimana : s = df error MSE = error MS dalam tabel ANOVA (Within Group MS) n = besar sampel

  9. PADA CONTOH SEBELUMNYA : s = 20 MSE = 100,9 n = 6 LSD = t0,025 , 20 ( 2 . 100,9 / 6 ) = 2,09 . 5,8 = 12,12 xi 62 72 76 85 B C D A

  10. PASANGAN KELOMPOK YANG BERBEDA : B dengan D B dengan A C dengan A
