Anda dapat menggunakan sintaks berikut untuk menghitung korelasi antara dua kolom di pandas DataFrame:<\/span><\/p>\n

 df[' column1<\/span> ']. corr<\/span> (df[' column2<\/span> '])\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan sintaksis ini dalam praktiknya.<\/span><\/p>\n
 Contoh 1: Hitung korelasi antara dua kolom<\/strong><\/h3>\n
 Kode berikut menunjukkan cara menghitung korelasi antar kolom di pandas DataFrame:<\/span><\/p>\n
 import<\/span> pandas as<\/span> pd\n\n#createDataFrame\n<\/span>df = pd. DataFrame<\/span> ({' points<\/span> ': [25, 12, 15, 14, 19, 23, 25, 29],\n                   ' assists<\/span> ': [5, 7, 7, 9, 12, 9, 9, 4],\n                   ' rebounds<\/span> ': [11, 8, 10, 6, 6, 5, 9, 12]})\n\n#view first five rows of DataFrame\n<\/span>df. head<\/span> ()\n\n        points assists rebounds\n0 25 5 11\n1 12 7 8\n2 15 7 10\n3 14 9 6\n4 19 12 6\n\n#calculate correlation between points and assists\n<\/span>df[' points<\/span> ']. corr<\/span> (df[' assists<\/span> '])\n\n-0.359384\n<\/strong><\/pre>\n
 Koefisien korelasinya sebesar -0,359<\/strong> . Karena korelasi ini negatif, hal ini menunjukkan bahwa poin dan assist berkorelasi negatif.<\/span><\/p>\n
 Dengan kata lain, seiring bertambahnya nilai pada kolom poin, maka nilai pada kolom assist cenderung menurun.<\/span><\/p>\n
 Contoh 2: Hitung Signifikansi Korelasi<\/strong><\/span><\/h3>\n
 Untuk menentukan apakah koefisien korelasi signifikan secara statistik atau tidak, Anda dapat menggunakan fungsi pearsonr(x, y)<\/strong> dari perpustakaan SciPy<\/a> .<\/span><\/p>\n
 Kode berikut menunjukkan cara menggunakan fungsi ini dalam praktiknya:<\/span><\/p>\n
 import<\/span> pandas as<\/span> pd\nfrom<\/span> scipy. stats<\/span> import<\/span> pearsonr\n\n#createDataFrame\n<\/span>df = pd. DataFrame<\/span> ({' points<\/span> ': [25, 12, 15, 14, 19, 23, 25, 29],\n                   ' assists<\/span> ': [5, 7, 7, 9, 12, 9, 9, 4],\n                   ' rebounds<\/span> ': [11, 8, 10, 6, 6, 5, 9, 12]})\n\n#calculate p-value of correlation coefficient between points and assists\n<\/span>pearsonr(df[' points<\/span> '], df[' assists<\/span> '])\n\n(-0.359384, 0.38192)\n<\/strong><\/pre>\n
 Nilai keluaran pertama menampilkan koefisien korelasi (-0,359384) dan nilai kedua menampilkan nilai p (0,38192) yang terkait dengan koefisien korelasi tersebut.<\/span><\/p>\n

 Karena nilai p<\/a> tidak kurang dari \u03b1 = 0,05, kami menyimpulkan bahwa korelasi antara poin dan assist tidak signifikan secara statistik.<\/span><\/p>\n
