** Your General Comment **
** Describe what you see on your first 10 clicks **
It looks like the program keep track of how long the program has been operating, so that when you click on it displays the time, so you can record start and stop time.

** Your average time interval for 20 time intervals **
T20 = 174.8867s, T1 = 168.289s
T20 - T1 = 6.5976s
6.5976s/20 = .32988s

** Your general comment to this point **
N/A
** Why did you observe only certain time intervals? **
I think because it averages. 1 micro-second or even 1 milli-second for that matter is a very short time interval, therefore the program most likely puts out the next closest digit counted. This does not mean that the program is flawed or useless. We have no other timer to compare it to, so for this experiment it is the standard; because it can record time more accurately than you or I in our head. Not to mention, it has a greater resolution than your average stopwatch or wristwatch.
** What did you see when you looked at the differences between time successive time intervals? **
It looks as if the timer program has preregistered inputs that it uses to count. Therefore, that is why you end up with similiar numbers.

** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
I think because there is too much time in between actions, leaving room for more inequalities.
** Do you think this program is accurate to .1 or .01 ... **
c. The TIMER program is capable of determining the time between two events accurately to within about .001 second.
