Dari data Laki laki di atas diperoleh :
L0 = 0,344
LTabel
= 0,201
Trima H0 jika L0 < LTabel
Kesimpulan
: Tolak H0 artinya Data Tidak
Berdistribusi Normal

Dari data Perempuan di atas diperoleh :
L0 = 0,335
LTabel =
0,201
Trima H0 jika L0 < LTabel
Kesimpulan
: Tolak H0 artinya Data Tidak Berdistribusi Normal
II. Karena data Tidak
Berdistribusi Normal maka digunakan Uji Mann Whitney.
