The quartile
deviation of the data in the table abobe is........
Simpangan
kuartil dari data pada tabel di atas adalah..........
The location of Q ₁
= k₁
= 6,25
Lokasi Q₁ = k₁
= 6,25
Solution :
Q₁ is located at the class 59
Penyelesaian Q₁ terletak pada kelas 59
It means/berarti: Tᵇ = 57,5, F₁=2, f₁=4, p=3
Q₁ = Tb +
57,5 +
=60,69
The location
of Q₃ = k₃
= 18,75
Lokasi Q₃ = k₃
= 18,75
Q₃ is
located at the class 69
Q₃ terletak pada kelas 69
It means / berarti : Tb = 63,5
, F₃=5, f₃=5, p=7
Q₁ = Tb +
63,5 +
= 82,75
Qd =
(Q₃ - Q₁) =
( 82,75 – 60,69)
= 11,03
So, its quartile deviation is 11,03
Jadi, simpangan
kuartilnya adalah adalah 11,03
