Diketahu data 3, 4, 8, 7, 4, 8, 4, 9, 10, 8, 3, 5, 12, 7. A. Jangkaian data b. Mean

A. 9

B. 23

A. Jangkauan Data (Range)

Range = Data terbesar – Data terkecil

= 12 – 3

= 9

B. Mean

$bar{x}=frac{1}{n} left ( x_1+x_2+ cdots +x_n right )$

$= frac{1}{14} (3 + 4 + 8 + 7 + 4 + 8 + 4 + 9 + 10 + 8 + 3 + 5 + 12 + 7)$

$= frac{1}{4} (92)$

$= 23$

* Semoga membantu :3
