Physics Practical Mark Sheme help!

[Saturation]

Hi!

Can someone explain to me what this mark scheme means (it's about the percentage uncertainity) :

http://www.xtremepapers.me/CIE/Internat ... 5_ms_3.pdf

section ; a (iii) The 1st line.

Does it mean that the absolute uncertainty can be from 1 to 5 , or from 1^0 to 5^0 ( which makes no sense at all!)!
Just want to confirm!
Thanks!

Ya it means absolute uncertanity is correct for any value from 1 deg to 5 deg..

% uncertanity= (absolute uncertanity)* 100/ ( obtained value)
