7+3+4+x+8+6+3+6+7+9+4+3+7+8 / 14 = 6 75+x = 84 x = 84 - 75 x = 9
nah jadi x = 9
median = 3,3,3,4,4,6,6,7,7,7,8,8,9,9 = 6+7/2 = 13/2 = 7,5 modus = 7

A. rata -rata = jumlah nilai / banyak nilai 6 = 7+3+4+x+8+6+3+6+7+9+4+3+7+8 / 14 6 = 75+x / 14 6 × 14 = 75 + x 84 = 75 + x 84 - 75 = x 9 = x
median ( nilai tengah ) = 3,3,3,4,4,6,6,7,7,7,8,8,9,9 = 6 + 7 /2 = 14/2 =7 b. modus ( nilai yang sering muncul) = 3 dan 7
7+3+4+x+8+6+3+6+7+9+4+3+7+8 / 14 = 6
75+x = 84
x = 84 - 75
x = 9
nah jadi x = 9
median = 3,3,3,4,4,6,6,7,7,7,8,8,9,9 = 6+7/2 = 13/2 = 7,5
modus = 7
6 = 7+3+4+x+8+6+3+6+7+9+4+3+7+8 / 14
6 = 75+x / 14
6 × 14 = 75 + x
84 = 75 + x
84 - 75 = x
9 = x
median ( nilai tengah ) = 3,3,3,4,4,6,6,7,7,7,8,8,9,9
= 6 + 7 /2
= 14/2
=7
b. modus ( nilai yang sering muncul) = 3 dan 7
