Urutan data:

1, 1, 2, 2, 3, 5, 5, 5, 5, 6, 7, 8, 8, 8, 10, 10, 14, 15, 17, 19

n (banyak data)= 20

Data ke1 = 1

Data ke2 = 1

Data ke3= 2

Dst

a) mean = jumlah data/banyak data 

                = 151/20

                = 7,55

b) median = x  n/2 + (n/2 + 1)

                                  2

= x 20/2 + (20/2 +1)

                  2

= x 10 + x 11

            2 

= (x10 + x11)

             2

= 6+7

      2

= 12, 5

 

c) modus/nilai yg sering muncul = 5
