Uji McNemar<\/strong> digunakan untuk menentukan apakah terdapat perbedaan proporsi yang signifikan secara statistik antara data berpasangan.<\/span><\/p>\n

Tutorial ini menjelaskan cara melakukan tes McNemar di R.<\/span><\/p>\n

Contoh: Tes McNemar di R<\/strong><\/span><\/h2>\n

Katakanlah peneliti ingin mengetahui apakah video pemasaran tertentu dapat mengubah opini masyarakat terhadap undang-undang tertentu. Mereka mensurvei 100 orang untuk mengetahui apakah mereka mendukung undang-undang tersebut atau tidak. Kemudian mereka menunjukkan video pemasaran tersebut kepada 100 orang dan mensurvei mereka lagi setelah video tersebut selesai.<\/span><\/p>\n

Tabel berikut menunjukkan jumlah total orang yang mendukung undang-undang tersebut sebelum dan sesudah menonton video tersebut:<\/span><\/p>\n\n\n\n\n\n\n
<\/th>\n Video sebelum pemasaran<\/span><\/th>\n<\/tr>\n
Video setelah pemasaran<\/span><\/td>\n Mendukung<\/strong><\/span><\/td>\n Tidak tahan<\/strong><\/span><\/td>\n<\/tr>\n
Mendukung<\/strong><\/span><\/td>\n 30<\/span><\/td>\n 40<\/span><\/td>\n<\/tr>\n
Tidak tahan<\/strong><\/span><\/td>\n 12<\/span><\/td>\n 18<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Untuk menentukan apakah terdapat perbedaan yang signifikan secara statistik pada proporsi masyarakat yang mendukung hukum sebelum dan sesudah menonton video tersebut, kita dapat melakukan uji McNemar.<\/span><\/p>\n

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

Pertama, buat dataset dalam bentuk raster.<\/span><\/p>\n

 #create data<\/span>\ndata <- matrix(c(30, 12, 40, 18), nrow = 2,\n    dimnames = list(\"After Video\" = c(\"Support\", \"Do Not Support\"),\n                    \"Before Video\" = c(\"Support\", \"Do Not Support\")))\n\n#view data\n<\/span>data\n\n                Before Video\nAfter Video Support Do Not Support\n  Bracket 30 40\n  Do Not Support 12 18\n<\/strong><\/pre>\n
 Langkah 2: Lakukan tes McNemar.<\/strong><\/span><\/p>\n
 Selanjutnya, lakukan pengujian McNemar menggunakan sintaks berikut:<\/span><\/p>\n
 mcnemar.test(x,y=NULL,benar=BENAR)<\/span><\/strong><\/p>\n
 Emas:<\/span><\/p>\n
    \n
  •  x<\/strong> : tabel kontingensi dua dimensi dalam bentuk matriks, atau objek faktor.<\/span><\/li>\n
  •  y<\/strong> : objek faktor; diabaikan jika x adalah matriks.<\/span><\/li>\n
  •  benar<\/strong> : BENAR = menerapkan koreksi kontinuitas saat menghitung statistik pengujian; FALSE = tidak menerapkan koreksi kontinuitas.<\/span><\/li>\n<\/ul>\n
     Secara umum, koreksi kontinuitas harus diterapkan ketika beberapa hitungan dalam tabel rendah. Biasanya, koreksi ini diterapkan ketika jumlah sel kurang dari 5.<\/span><\/p>\n
     Kami akan melakukan tes McNemar dengan dan tanpa koreksi kontinuitas, hanya untuk mengilustrasikan perbedaannya:<\/span><\/p>\n
     #Perform McNemar's Test with continuity correction<\/span>\nmcnemar.test(data)\n\n\tMcNemar's Chi-squared test with continuity correction\n\ndata:data\nMcNemar's chi-squared = 14.019, df = 1, p-value = 0.000181\n\n#Perform McNemar's Test without continuity correction<\/span>\nmcnemar.test(data, correct=FALSE) \n\n\tMcNemar's Chi-squared test\n\ndata:data\nMcNemar's chi-squared = 15.077, df = 1, p-value = 0.0001032<\/strong><\/pre>\n
     Dalam kedua kasus tersebut, nilai p dari pengujian tersebut kurang dari 0,05, sehingga kami menolak hipotesis nol dan menyimpulkan bahwa proporsi masyarakat yang mendukung hukum sebelum dan sesudah menonton video pemasaran berbeda secara statistik.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
