rata rata simpangan dari data 4,7,5,6,8,6 adalah..

Matematika

[tex]x = \frac{4 + 7 + 5 + 6 + 8 + 6}{6} \\ x = \frac{30}{6} \\ x = 5[/tex]
Simpangan rata² →
[tex] = \frac{ |4 - x| + |7 - x| + |5 - x| + 2|6 - x| + |8 - x| }{6} \\ = \frac{ |4 - 6| + |7 - 6| + |5 - 6| + 2 |6 - 6| + |8 - 6| }{6} \\ = \frac{2 + 1 + 1 + 0 + 2}{6} \\ = \frac{6}{6} \\ = 1[/tex]
