1 DATA ANALYSIS descriptive

2 (Bivariat, Multivariat)
Jenis Analisis Data Deskriptif (Univariat) Inferensial (Bivariat, Multivariat)

3 Analisis Deskriptif

4 Analisis Deskriptif

5 Distribusi Frekuensi Grouped Data Ungrouped Data

6 Batas Atas – Batas Bawah (Tepi atas + Tepi Bawah)
Distribusi Frekuensi 10-14 Batas Bawah = 9,5 (10 - 0,5) (Tepi bawah - 0,5) Batas Atas = 14,5 (14 + 0,5) (Tepi atas + 0,5 ) Panjang Kelas = Batas Atas – Batas Bawah Titik Tengah (Xn)= (Tepi atas + Tepi Bawah) 2

7 Menyusun interval kelas
Jumlah Kelas (k) k = 1 + 3,3 Log n Distribusi Frekuensi Range (R) Data Max – Data Min Panjang Kelas (I) I = R : k Menyusun interval kelas Interval per kelas = tepi bawah + ( I – 1 )
