Z-score tells us a little story….

by Kumara Kaluarachchi

(June 11, Colombo, Sri Lanka Guardian) Last week, the University grants commission of Sri Lanka has issued the minimum cut off z scores for selection to various courses of study in respect of each district. I was interested in the z scores for Medicine. When I went through the minimum Z score for each district, this is what I got:

1 Colombo - 1.991
2 Matara - 1.9864
3 Galle - 1.9794
4 Kandy - 1.9071
5 Kurunegala - 1.9053
6 Kalutara - 1.8841
7 Jaffna - 1.8814
8 Hambantota - 1.8813
9 Kegalla - 1.8629
10 Ratnapura - 1.8445
11 Gampaha - 1.8123
12 Ampara - 1.8098
13 Vavuniya - 1.7283
14 Matale - 1.7241
15 Anuradhapura - 1.6887
16 Batticaloa - 1.6335
17 Tincomalee - 1.6175
18 Monaragala - 1.6123
19 Badulla - 1.5891
20 Puttalam - 1.5867
21 Polonnaruwa - 1.4108
22 Nuwaraeliya - 1.2731
23 Kilinochchi - 0.8233
24 Mulativu - 0.8039

Colombo got the highest Z score and Mulativu got the lowest. Jaffna is in the 7th place just above Hambantota.

Different people could interpret this data in different manner. I do not like to do that here in this article. All I want is you guys to look in to the data and THINK!
