. Assume the error in timing when starting and stopping the stopwatch is +0.2 seconds. So, if a single period is measured, the entire 0.2 second error affects this one period. Suppose the stopwatch is used to record 10 continuous periods, how much of this error affects a single period? How much for 50 continuous periods?

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for
