Consist of description using term where the information are non-numeric.
For data of qualitative we had done survey about the amount of students in each state.

Central distribution
the value that occurs the most often in a set of data.
Mode = is the class interval which have the highest frequency
The mode for this survey is the clas interval 1 – 5 which appears thirty-eight times (38).
Mode
The median of a distribution with a discrete random variable depends on whether the number of terms in the distribution is even or odd.
m = medianL = lower boundaryF = median classC = size of classN = class m = L + (1/2N – F)C f
m = 0.5 + (1/2 (65) -0 ) 38

= 5.77 times
Mean
Following on our comments, we can make a simple and clear conclusion that the Institut Pendidikan Guru Kampus Perlis students rarely returned their home in every month per semester. There are most from around north like Kelantan, Pahang and so on. the students who comes from north are mostly back to their home in every weeks.This data was proven through the survey that we have done. Among 65 students that we ask how much times they returned home and we get the result that 38 of them not rarely back their home around only once until five times in a semester.
Conclusion
From the data of qualitative are shows most students who studies here are from Kedah and Perak for students from group PPISMP 3RD semester intake July 2009. Each have 18 and 12 students included male and female. For the state of Selangor, Pahang and Johor only a students in each state get in and they are the best students from else who the lucky to continue their future study and become a teachers.
