Uji Kolmogorov - Smirnov

Uji Kolmogorov - Smirnov

         Uji 1 sampel kolmogorov-Smirnov digunakan untuk mengetahui apakah distribusi nilai-nilai sampel yang teramati sesuai dengan distribusi teoritis tertentu (normal, uniform, poisson, eksponensial).  Uji Kolmogorov-Smirnov beranggapan bahwa distribusi variabel yang sedang diuji bersifat kontinu dan pengambilan sampel secara acak. Dengan demikian uji ini hanya dapat digunakan, bila variabel diukur paling tidak dalam skala interval.
Prinsip dari uji Kolmogorov–Smirnov adalah menghitung selisih absolut antara fungsi distribusi frekuensi kumulatif sampel dan fungsi distribusi frekuensi kumulatif teoritis pada masing-masing interval kelas. 
  • Hipotesis yang diuji dinyatakan sebagai berikut (dua sisi):
         H0: Data mengikuti sebaran normal
        H1: Data tidak mengikuti sebaran nomal
  • Statistik Uji
  • Taraf nyata = α
  • Wilayah Kritis
   Tolak Ho jika D > D tabel (α,n)

Tabel dalam Statistika

Pada kesempatan kali ini saya akan mempost tabel distribusi probabilitas normal baku, tabel binominal dan tabel tabel lainnya, bagi yang membutuhkan silahkan download melalui link dibawah ini :

1. Tabel Distribusi Probabilitas
2. Tabel Binomial
3. Tabel Kolmogorov-Smirnov

Uji Chi kuadrat -->> kasus dua sampel independen

fungsi :

- bila penelitian terdiri dari frekuensi-frekuensi dalam kategori diskrit
- sama dengan uji eksak fisher, hanya data disusun dalam tabel b x k , dengan b = banyak baris dan k = banyak kolom
- ekspetasi setiap sel ≥ 5

spesifikasi :

-data disusun dalam tabel kontingensi
-digunakan untuk menguji independensi



Langkah-langkah pengujian :

Ho : p(I) = p(II)
H1 : uji satu arah atau dua arah
α    : Tarafnyata

Statistik uji :

a.    JIKA DATA DISUSUN DALAM TABEL  2 x 2

1. jika ukuran sampel n < 20 maka gunakan uji eksak fisher
2. jika ukuran sampel n ≥ 20 maka gunakan uji χ² sebagai berikut :

 b. JIKA DATA DISUSUN DALAM TABEL bx k

dengan n > 40 maka gunakan uji  χ² sebagai berikut :


 
Oij : frekuensi observasi baris i dan kolom j
Eij : frekuensi ekspetasi baris i dan kolom j

Kriteria uji :

uji satu pihak = Tolak Ho jika  χ² ≥  χ²α, terima dalam hal lainnya

uji dua pihak = Tolak Ho jika  χ² ≥  χ²α/2, terima dalam hal lainnya


contoh soal :
berdasarkan standar badan telekomunikasi internasional, dengan menggunakan data ASR dari panggilan SLJJ dari kota kecil (KK) dan kota besar (KB) diperoleh hasil sebagai berikut :

Dengan α=5%, apakah PT. TELKOM telah mencapai World Class Operator (WCO) ?

jawab :

Ho : p(KB) = p(KK)
       PT. TELKOM telah mencapai World Class Operator (WCO) 

H1 : p(KB) ≠ p(KK)
       PT. TELKOM belum mencapai World Class Operator (WCO)

 α : 5%

 




 








              statistik uji :
 

            kriteria uji :

            α   = 5%
db       db = (b-1)(k-1)=(4-1)(2-1)=3
maka   χ²α/2  = 9,35
               
              χ² = 1,2255    <   χ²α/2  = 9,35
    a        maka Ho diterima, artinya PT. TELKOM telah mencapai World Class Operator (WCO)
