In this paper I compare the quality of the fit of a simple power law model of cosmic expansion to the standard $\Lambda$CDM model. I analyze a data set consisting of cosmic chronometer, standard ruler, and standard candle measurements, finding that the $\Lambda$CDM model provides a better fit to most combinations of these data than does the power law model
