1. A method of indicating a rate of change in a user'"'"'s analyte level with reduced noise-induced variation, comprising:

  • determining, with a processor, a first filtered value associated with analyte related data measured by an in vivo sensor during a first predetermined time period;

    determining, with the processor, a second filtered value associated with analyte related data measured by the in vivo sensor during a second predetermined time period, wherein the first predetermined time period is greater than the second predetermined time period;

    determining, with the processor, (a) a rate of change of an analyte level based, at least in part, on the analyte related data, and (b) a rate of change variation;

    generating, with the processor, a weighted average value based upon the first filtered value and the second filtered value such that the first filtered value is weighted more than the second filtered value when the rate of change is greater than the rate of change variation and such that the second filtered value is weighted more than the first filtered value when the rate of change is less than the rate of change variation;

    determining, with the processor, a filtered analyte value based at least in part on the weighted average value and a predetermined parameter to reduce noise-induced variation; and

    dynamically displaying an indication based on the filtered analyte value to a user on a display of an analyte monitoring device.
