Hukum bilangan besar

Dalam teori probabilitas, hukum bilangan besar adalah hukum matematika yang menyatakan bahwa rata-rata hasil yang diperoleh dari sejumlah besar sampel acak independen konvergen ke nilai sebenarnya, jika ada. Secara lebih formal, hukum bilangan besar menyatakan bahwa jika diberikan sampel berisi nilai-nilai yang independen dan terdistribusi secara identik, nilai rata-rata sampel akan konvergen ke nilai rata-rata sebenarnya.

The law of large numbers is a fundamental concept in probability theory and statistics, tying together theoretical probabilities that we can calculate to the actual outcomes of experiments that we empirically perform. explained Business Insider
