hitunglah rataan harmonis dari data 2,3,4,6

Kelas : XI SMA
Mapel : Matematika Wajib
Bab : Statistika
Indikator : Rataan Harmonis Data Tunggal

Langkah Penyelesaian dan Jawaban :

Data : 2, 3, 4, 6
Banyak data (n) = 4

[tex]H = \frac{n}{\sum(\frac{1}{x_i})} \\\\ H = \frac{4}{\frac{1}{2} + \frac{1}{3} + \frac{1}{4} + \frac{1}{6}} \\\\ H = \frac{4}{\frac{6}{12} + \frac{4}{12} + \frac{3}{12} + \frac{2}{12}} \\\\ H = \frac{4}{\frac{15}{12}} \\\\ H = 4 \times \frac{12}{15}\\\\ H = \boxed{3,2}[/tex]
