** Your General Comment **
** Describe what you see on your first 10 clicks **
The first column appears to be constant times were the clock had been stopped. The second column looks to be the difference between each timed stop.

** Your average time interval for 20 time intervals **
.1156
I subtracted the first time from the last and then divided by the total number of intervals.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.09375,2
.109375,4
.125,11
.140625,2
** Your general comment to this point **
In the first occurrence there is no interval. Should I start my observations from the second accurance ?
** Why did you observe only certain time intervals? **
It is not useless but it is not totally accurate. It is as accurate as needed for educational purposes.
** What did you see when you looked at the differences between time successive time intervals? **
negatives are the first difference's that I noticed, and very short intervals would be the second thing I observed. I do not understand how time could be measured backwards.
** Your time intervals for 7 complete breaths: **
1 , 1.968018
2 , 4.593018
3 , 7.656006
4 , 10.59302
5 , 13.84302
6 , 16.6709
7 , 19.57788
8 , 22.23389
9 , 25.46802
10 , 27.7959
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
Human function is sporadic and when thinking about involuntary functions the functions may be altered.
** Do you think this program is accurate to .1 or .01 ... **
a. The TIMER program is capable of determining the time between two events accurately to within about .1 second.
** Copy of a few lines of your spreadsheet from the TIMER program. **
