Advanced ground-based gravitational-wave detectors have the capability of measuring tidal influences in binary neutron star systems. In this work, we report on the statistical uncertainties in measuring tidal deformability by using a full Bayesian parameter estimation implementation. We show how simultaneous measurements of chirp mass and tidal deformability can be used to constrain the neutron star equation of state. We also study the effect of systematic and statistical error on these measurements. We notably find that systematic error between post-Newtonian waveform families can significantly bias the estimation of tidal parameters, thus motivating the development of waveform models that are more reliable at high frequencies.
