Jawaban:

Data : 27,28,29,30,31,32,33,34,35

Frekuensi : 5,6,5,6,6,3,4,7,8

Nilai ke - : 1-5, 6-11, 12-16, 17-22, 23-28, 29-31, 32-35, 36-42, 43-50

Mean/Rata-rata = Jumlah data/Banyak Data

Jumlah data = 27×5 + 28×6 + 29×5 + 30×6 + 31×6 + 32×3 + 33×4 + 34×7 + 35×8 = 135 + 168 + 145 + 180 + 186 + 96 + 132 + 238 + 280 = 1560

Banyak data = 5+6+5+6+6+3+4+7+8 = 50

Mean = 1560 / 50 = 31,2

Median = 5+6+5+6+6+3+4+7+8 = 50 ( Genap )

             = nilai ke- n/2 + nilai ke- n/2+1 / 2

             = 50/2 + 50/2+1 /2

             = nilai ke- 25 + nilai ke- 26 / 2

             = 31 + 31 / 2

             = 62 / 2

             = 31

Modus = 35

27 = 5

28 = 6

29 = 5

30 = 6

31 = 6

32 = 3

33 =4

34 = 7

35 = 8
