Fast Radio Bursts (FRBs) are bursts of radio waves detected at great distances from space. Some FRBs are observed to repeat while some others not. One important question concerning astrophysicists today is whether all FRBs repeat. Recently, the Canadian Hydrogen Intensity Mapping Experiment (CHIME) published a master catalog of FRB detections for both repeating and non-repeating FRBs. This is the largest FRB database published to date. With the data in this catalog, we investigate whether repeaters and non-repeaters may show up as statistically different categories in certain parameter space. We focus on the FRB arrival time and fluence and study the repetition behavior in the fluence ratio vs. waiting time two-dimensional space for each pair of bursts for repeating FRBs as well the lower limits of both parameters for non-repeaters. From this graph we can determine if repeaters and non-repeaters indeed occupy different phase spaces, which can shed light on whether they have distinct origins or rather form a continuum in terms of repetition rate, i.e. the apparent non-repeaters are simply repeaters with slower repetition rates.
