Tabel distribusi frekuensi adalah tabel yang menampilkan frekuensi berbagai kelas data.<\/span><\/p>\n

Misalnya, tabel distribusi frekuensi berikut menunjukkan frekuensi untuk lima kelas berbeda:<\/span><\/p>\n\n\n\n\n\n\n\n\n
Kelas<\/strong><\/span><\/th>\n Frekuensi<\/strong><\/span><\/th>\n<\/tr>\n
1 \u2013 10<\/span><\/td>\n 20<\/span><\/td>\n<\/tr>\n
11 \u2013 20<\/span><\/td>\n 21<\/span><\/td>\n<\/tr>\n
21 \u2013 30<\/span><\/td>\n 16<\/span><\/td>\n<\/tr>\n
31 \u2013 40<\/span><\/td>\n 5<\/span><\/td>\n<\/tr>\n
41 \u2013 50<\/span><\/td>\n 4<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Anda dapat mencari titik tengah setiap kelas dengan menjumlahkan batas bawah dan batas atas kelas, lalu membaginya dua:<\/span><\/p>\n

Titik tengah kelas<\/strong> = (batas kelas bawah + batas kelas atas) \/ 2<\/span><\/p>\n

Tabel berikut menunjukkan cara menghitung titik tengah setiap kelas:<\/span><\/p>\n\n\n\n\n\n\n\n\n
Kelas<\/strong><\/span><\/th>\n Frekuensi<\/strong><\/span><\/th>\n Titik tengah<\/strong><\/span><\/th>\n<\/tr>\n
1 \u2013 10<\/span><\/td>\n 20<\/span><\/td>\n (1+10) \/ 2<\/span><\/td>\n<\/tr>\n
11 \u2013 20<\/span><\/td>\n 21<\/span><\/td>\n (11+20) \/ 2<\/span><\/td>\n<\/tr>\n
21 \u2013 30<\/span><\/td>\n 16<\/span><\/td>\n (21+30) \/ 2<\/span><\/td>\n<\/tr>\n
31 \u2013 40<\/span><\/td>\n 5<\/span><\/td>\n (31+40) \/ 2<\/span><\/td>\n<\/tr>\n
41 \u2013 50<\/span><\/td>\n 4<\/span><\/td>\n (41+50) \/ 2<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Oleh karena itu, kita memiliki titik tengah berikut:<\/span><\/p>\n\n\n\n\n\n\n\n\n
Kelas<\/strong><\/span><\/th>\n Frekuensi<\/strong><\/span><\/th>\n Titik tengah<\/strong><\/span><\/th>\n<\/tr>\n
1 \u2013 10<\/span><\/td>\n 20<\/span><\/td>\n 5.5<\/span><\/td>\n<\/tr>\n
11 \u2013 20<\/span><\/td>\n 21<\/span><\/td>\n 15.5<\/span><\/td>\n<\/tr>\n
21 \u2013 30<\/span><\/td>\n 16<\/span><\/td>\n 25.5<\/span><\/td>\n<\/tr>\n
31 \u2013 40<\/span><\/td>\n 5<\/span><\/td>\n 35.5<\/span><\/td>\n<\/tr>\n
41 \u2013 50<\/span><\/td>\n 4<\/span><\/td>\n 45.5<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Kapan titik tengah kelas digunakan?<\/strong><\/span><\/h2>\n

Titik tengah kelas sering digunakan ketika Anda ingin membuat histogram untuk memvisualisasikan nilai dalam tabel frekuensi.<\/span><\/p>\n

Histogram mencantumkan kelas-kelas di sepanjang sumbu x suatu grafik dan menggunakan batang untuk mewakili frekuensi setiap kelas di sepanjang sumbu y. Setiap bar dipusatkan di tengah-tengah kelasnya<\/strong> .<\/span><\/p>\n

Histogram berikut memberikan representasi visual data dari tabel frekuensi sebelumnya:<\/span> <\/p>\n

\"Titik<\/p>\n

Perhatikan bagaimana setiap bar dipusatkan di tengah-tengah kelasnya:<\/span> <\/p>\n

\"Contoh<\/p>\n

Saat membuat histogram dengan tangan, akan sangat berguna jika mengetahui titik tengah kelas sehingga Anda tahu di mana menempatkan batangnya.<\/span><\/p>\n

Namun, sebagian besar perangkat lunak statistik mampu secara otomatis memusatkan batang histogram di sekitar titik tengah kelas, sehingga Anda biasanya tidak perlu mencari sendiri titik tengah tersebut secara manual.<\/span><\/p>\n
