Kekerapan bagi setiap nombor
1: Ada 6 kali
2: Ada 2 kali
4: Ada 2 kali
5: Ada sekali
4
Sambungan
Oleh kerana no 1 mempunyai kekerapan paling banyak iaitu sebanyak 6 kali, maka no 1 merupakan nilai bagi Mod
5
Median
Nilai yang berada ditengah-tengah data, dimana data tersebut mestilah disusun terlebih dahulu mengikut tertib menaik ataupun mengikut tertib menurun.
Contoh: 4,2,1,1,1,1,1,1,2,4,5
Kena susun terlebih dahulu
1,1,1,1,1,1,2,2,4,4,5 ataupun 5,4,4,2,2,1,1,1,1,1,1
Data ini mempunyai 11bilangan. Nombor yang berada ditengah ialah pada kedudukan ke6 iaitu no 1. Maka Median ialah 1
6
Min

Jumlah nilai data dibahagi dengan Bilangan Data
7
Min
Contoh: 4,2,1,1,1,1,1,1,2,4,5. Cari nilai Min
Jumlah data ialah 4+2+1+1+1+1+1+1+2+4+5=23
Bilangan Data ialah 11
Maka Min ialah 23/11 =2.09
