If by "assign" you mean display points by varying sized circles, then 
yes. Open the layer's "Properties" window and go to the "Symbology" tab. 
As "Legend type"  select graduated symbol.  Then in "Classification 
field" select which column represents the +/- error. Then enter a number 
for "Number of classes" and click "classify". Now go thru the list of 
classes fone by one and set up each symbol as a different size using the 
"Size" entry, or different color using the "Style options".
