-From the histogram shown above, we can say that jitter is expected to be more fluctuated for longer sleep duration, and the relationship between the sleep duration and jitter can fit a polynomial curve of degree 2 as being shown below. A possible reason for this may be the overhead of the function call and operating system scheduling.
