** Your General Comment **
** Describe what you see on your first 10 clicks **
A table is displayed in which the first column lists the number for the amount of times the click to time event button was pushed, the second column gives the time of the event, and the third column gives the difference between that event and the event prior to it.

** Your average time interval for 20 time intervals **

I added all of the time intervals and divided by 20.

** Your general comment to this point **
** Why did you observe only certain time intervals? **
The timer program is not flawed or useless, it only provides an estimate to the nearest portion of a second instead of reporting actual real times which is impossible to record to many decimal places.
** What did you see when you looked at the differences between time successive time intervals? **
All of the differences are repeatable at least once. This shows that the timer program demonstrates repeatablility and is therefore useful statistically.
** Your time intervals for 7 complete breaths: **

** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
We would expect this because there is more variance in longer time periods than there are in shorter time periods.
** Do you think this program is accurate to .1 or .01 ... **
C because many of the intervals in the fast measurement were repeatable to 3 decimal places.
