Distribusi Frekuensi Generator

ini adalah script untuk meng-generate data nilai acak untuk pembuatan tabel distribusi frekuensi

Cara menggunakan

• harus sudah menginstall nodejs
• download scriptnya
• buka terminal/cmd
• jalankan perintah node test.js (versi statis) atau node rl.js (versi dinamis, sesuai inputan user)
