** Describe what you see on your first 10 clicks **
I see three columns, the first has the number of the click and the second has the time of the click, the third column has the time between each click.

** Your average time interval for 20 time intervals **
0.156994
I put them into excel and told excel to calculate the average. What was the easier way that you were talking about?
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
0.09375, 1
0.125, 1
0.140625, 4
0.15625, 6
0.171875, 6

** Your general comment to this point **
** Why did you observe only certain time intervals? **
The timer program seems to be only accurate up to about 0.01 of a second. Anything else beyond that I believe is just the program rounding. With this kind of accuracy, the program only becomes useless if we need time measurements with accuracy to 0.001 seconds.
** What did you see when you looked at the differences between time successive time intervals? **
It seems that the difference between each time interval can only be as 0.015625. I doubt that you are pressing the button with almost the exact same difference each time.
** Your time intervals for 7 complete breaths: **
4.265625
5.125
4.71875
5.953125
5.171875
4.625
4.140625
5.0625
4.84375
4.546875
** Your general comment to this point: **
You breath very very slowly...
** Why did you rarely, if ever, observe that same time interval twice? **
Alot of things have to be taken into account with something like breathing. If we are doing something, the rate increases or can decrease. There is also alot of time in between each breath, making it less likely to have the same time.
** Do you think this program is accurate to .1 or .01 ... **
Looking at the differences between time intervals, I think that it is most likely a, but it could be b. I just find it hard to believe that the you were clocked with almost, if not, the exact same intervals.
