Rata-rata dari data di atas yaitu Rumus simpangan rata-rata SR Maka

Rata-rata dari data di atas yaitu

$x space ̅ equals fraction numerator 4 plus 7 plus 5 plus 6 plus 8 plus 6 over denominator 6 end fraction equals 6$ $x space ̅ equals fraction numerator 4 plus 7 plus 5 plus 6 plus 8 plus 6 over denominator 6 end fraction equals 6$

Rumus simpangan rata-rata SR

$S R equals fraction numerator vertical line x subscript 1 minus x bar vertical line plus vertical line x subscript 2 minus x bar vertical line plus midline horizontal ellipsis plus vertical line x subscript n minus x bar vertical line over denominator n end fraction$

Maka

$S R equals fraction numerator vertical line 4 minus 6 vertical line plus vertical line 7 minus 6 vertical line plus vertical line 5 minus 6 vertical line plus vertical line 6 minus 6 vertical line plus vertical line 8 minus 6 vertical line plus vertical line 6 minus 6 vertical line over denominator 6 end fraction space S R equals fraction numerator 2 plus 1 plus 1 plus 0 plus 2 plus 0 over denominator 6 space end fraction S R equals 6 over 6 equals 1 comma 0$
