This thesis investigates the parity-violating ep asymmetry based on the Run I data produced in Spring of 2002 by the E158 experiment, located at the Stanford Linear Accelerator Center. The main scientific objective of the experiment is the precision measurement of the weak mixing angle of the Standard Model. The ep asymmetry is an important background in the experiment and theoretically interesting in its own right, providing insights into the structure of the proton. The analysis centers upon identifying systematic error and consistency. The definite measurement of the ep asymmetry will await the final reprocessing of the data set during the Fall of 2002.
