Calculating uncertainty of local gravity

1. The problem statement, all variables and given/known data
My first lab report in physics requires me to calculate the value of local gravity. I did this using latitude and longitude. I must also state the uncertainty of my local gravity value. I have no clue how to do this. What am I basing my uncertainty on, and is there an equation for it? Thanks!!! :)
 
What are the assumptions made from the longitude/latitude formula?
