Uji Kruskal-Wallis<\/a> digunakan untuk menentukan apakah terdapat perbedaan yang signifikan secara statistik antara median tiga atau lebih kelompok independen.<\/span><\/p>\n

Ini dianggap setara nonparametrik dari ANOVA satu arah<\/a> .<\/span><\/p>\n

Tutorial ini menjelaskan cara melakukan tes Kruskal-Wallis dengan Python.<\/span><\/p>\n

Contoh: Tes Kruskal-Wallis dengan Python<\/strong><\/span><\/h3>\n

Peneliti ingin mengetahui apakah tiga jenis pupuk berbeda menyebabkan tingkat pertumbuhan tanaman yang berbeda. Mereka secara acak memilih 30 tanaman berbeda dan membaginya menjadi tiga kelompok yang terdiri dari 10 tanaman, memberikan pupuk berbeda pada setiap kelompok. Setelah sebulan, mereka mengukur tinggi tiap tanaman.<\/span><\/p>\n

Ikuti langkah-langkah berikut untuk melakukan uji Kruskal-Wallis untuk menentukan apakah median pertumbuhan sama di ketiga kelompok.<\/span><\/p>\n

Langkah 1: Masukkan datanya.<\/strong><\/span><\/p>\n

Pertama, kita akan membuat tiga tabel untuk menampung pengukuran tanaman untuk masing-masing dari tiga kelompok:<\/span><\/p>\n

 group1 = [7, 14, 14, 13, 12, 9, 6, 14, 12, 8]\ngroup2 = [15, 17, 13, 15, 15, 13, 9, 12, 10, 8]\ngroup3 = [6, 8, 8, 9, 5, 14, 13, 8, 10, 9]\n<\/strong><\/pre>\n
 Langkah 2: Lakukan tes Kruskal-Wallis.<\/strong><\/span><\/p>\n
 Selanjutnya, kita akan melakukan tes Kruskal-Wallis menggunakan fungsi kruskal()<\/a> dari perpustakaan scipy.stats:<\/span><\/p>\n
 from<\/span> scipy import<\/span> stats\n\n#perform Kruskal-Wallis Test<\/span> \nstats.kruskal(group1, group2, group3)\n\n(statistic=6.2878, pvalue=0.0431)\n<\/strong><\/pre>\n
 Langkah 3: Interpretasikan hasilnya.<\/strong><\/span><\/p>\n
 Uji Kruskal-Wallis menggunakan hipotesis nol dan alternatif berikut:<\/span><\/p>\n
 Hipotesis nol (H 0<\/sub> ):<\/strong> Median semua kelompok sama.<\/span><\/p>\n
 Hipotesis alternatif: (Ha):<\/strong> Median tidak<\/em> sama di semua kelompok.<\/span><\/p>\n
 Dalam hal ini, statistik ujinya adalah 6,2878<\/strong> dan nilai p yang sesuai adalah 0,0431<\/strong> . Karena nilai p kurang dari 0,05, kita dapat menolak hipotesis nol yang menyatakan median pertumbuhan tanaman untuk ketiga pupuk adalah sama. Kami memiliki cukup bukti untuk menyimpulkan bahwa jenis pupuk yang digunakan menyebabkan perbedaan pertumbuhan tanaman yang signifikan secara statistik.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
