Nilai simpangan rata rata dari data 3 2 5 3 4 6 4 5 4

Rata-rata = jumlah seluruh data ÷ banyak data
= 36 ÷ 9
= 4

Simpangan rata(Sr)
= |3-4|+|2-5|+|5-4|+|3-4|+|4-4|
+|6-4|+|4-4|+|5-4|+|4-4|
= 1+2+1+0+2+0+1+0
= 7

(3+2+5+3+4+6+4+5+4) :9 =4

SR=[3-4]+[2-4]+[5-4]+[3-4]+[4-4]+[6-4]+[4-4]+[5-4]+[4-4]
     = (-1-2+1-1+0+2+0+1+0) :9
