tentukan mean, median, dan modus berikut a. 6 6 5 4 6 7 5 4 8 7 b. 2 2 2 3 3 8 5 5 5 5 c. 6 8 5 10 6 9 3 11 4 7

a. 6 6 5 4 6 7 5 4 8 7
4,4,5,5,6,6,6,7,7,8
Mean = 4+4+5+5+6+6+6+7+7+8/10 = 58/10 = 5,8
median = 6+6/2=12/2 =6
modus= 6

b. 2 2 2 3 3 8 5 5 5 5
2 2 2 3 3 5 5 5 5 8
mean = 2+2+2+3+3+5+5+5+5+8 /10 = 40/10 =4
median = 3+5/2= 8/2= 4
modus = 5

c. 6 8 5 10 6 9 3 11 4 7
3,4,5,6,6,7,8,9,10,11
mean = 3+4+5+6+6+7+8+9+10+11 /10 = 69/10 =6,9
median = 6+7/2 = 13/2 = 6,5
modus = 6
