= (336+444+292) – {(48+66+48)2/(7+10+8)}
= (1072) – (162)2/25)

= 1072 – 1049,76
= 22,22

JK antar = {(ƩY1)2/n1 + (ƩY2)2/n2 + (ƩY3)2/n3} – {(ƩY)2/N}
= {(48)2/7 + (66)2/10 + (48)2/8} - {(48+66+48)2/(7+10+8)}

= (2304/7 + 4356/10 + 2304/8) - (162)2/25)

= (329,14 + 435,60 + 288,00) – 1049,76
= 1052,74 – 1049,76

= 2,98
JK dalam = JK total – JK antar

= 22,22 – 2,98
= 19,24

Maka nilai F hitung adalah :

JKa/(k-1)
F hitung = ------------------

JKd/(N-k-1)

2,98/(3-1)

F hitung = ----------------
--- 19,24/(25-3-1)

2,98/2

F hitung = ----------
-- 19,24/21
