Kesimpulan :
Output 1 : N =
7, A,B,C
Output 2 : Sig =
0,708 > 0,05
Output 3 : F
hitung = 10,005
F tabel = 3,55
Apabila F tabel
> F hitung
Maka Ho diterima
Apabila F tabel
< F hitung
Maka Ho ditolak
Ho = rata rata
tekanan darah orang peminum obat A,B,C adalah sama
Hi = rata rata
tekanan darah orang peminum obat A,B,C adalah tak sama
Output 4 :
Kesimpulan =
Menunjukan ada
perbedaan rata rata yang signifikan
Contohnya :
Macam tekanan
darah peminum obat A
Berbeda
signifikan dengan peminum obat C
Berbeda
signifikan dengan peminum obat B
Berbeda
