Banyak Data = 15 data
Median = ½( n + 1 ) = ½(16) = X8 = 7 [ X8 - X10 ]
Rumus :
Modus = Tb + ( d¹/( d¹ + d² ) ) . pk
Tb = Tepi bawah nilai dalam kelas
d¹ = selisih frekuensi kelas sebelum
d² = selisih frekuensi kelas sesudah
____________________________/
Modus = K( 30 - 34 ) dengan f = 14
Tb = 29,5
d¹ = 14 - 7 = 7
d² = 14 - 7 = 7
pk = [ 30,31,32,33,34 ] = 5
---
Modus = 29,5 + 7/14 × 5
Modus = 29,5 + ½ × 5
Modus = 29,5 + 2,5
Modus = 32 { b. }
Semoga bisa membantu
