Question

Tentukan mean, mediand dan modus dari setiap data berikut. a.8,5,6,8,7,8,9,6,8,9,8,4,5
b. 6,4,7,5,10,3,6,8,7,2,7,6

Answer 1

Mean = jumlah data : banyak data
a. 8,5,6,8,7,8,9,6,8,9,8,4,5
mean = 8+5+6+8+7+8+9+6+8+9+8+4+5 : 13
mean = 91 : 13 = 7
b. 6,4,7,5,10,3,6,8,7,2,7,6
mean =6+4+7+5+10+3+6+8+7+2+7+6 : 12
mean = 71 : 12 = 5,19 ≈ 6

Median
a. 4,5,5,6,6,7,8,8,8,8,8,9,9
Me = 8
b. 2,3,4,5,6,6,6,7,7,7,8,10
Me = 6+6 : 2 =6

Modus
a. 4,5,5,6,6,7,8,8,8,8,8,9,9
Mo = 8
b. 2,3,4,5,6,6,6,7,7,7,8,10
mo = 6 & 7
