Answer 1

Mean = 4+3+5+6+7+5+8+7+7+2 / 10 = 5,4
Median = 2, 3, 4, 5, 5, 6, 7, 7, 7, 8 = 5+6 / 2 = 5,5
Modus = 7

Answer 2

Urutan data = 2, 3, 4, 5, 5, 6, 7, 7, 7, 8
mean= 2+3+4+5+5+6+7+7+7+8
        = 54 / 10
         = 5,4
 (rumusnya= jumlah nilai/banyaknya data)
median = 5 + 6
            = 11/2
            = 5,5
modus = 7
