** Your General Comment **
** Describe what you see on your first 10 clicks **
I see three columns of numbers, the first column tells how many times I have clicked on the timing button, the second column of numbers is how long the program has been running, and the third column is the amount of time in which the button was last clicked on.

** Your average time interval for 20 time intervals **
0.136
I added the first 20 numbers together then divided by 20.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.109375, 1
.125, 10
.140625, 6
.15625, 1
.203125, 1
** Your general comment to this point **
** Why did you observe only certain time intervals? **
It means that the timer program is counting by a certain interval.
** What did you see when you looked at the differences between time successive time intervals? **
it always ends with 0.00563, 0.00125, or 0.00625
** Your time intervals for 7 complete breaths: **
4.890625
6.140625
7.09375
6.234375
9.6875
6.921875
8.15625
8.53125
8.53125
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
because with larger time intervals, there is more precision in seconds and milliseconds rather than hundredths of seconds.
** Do you think this program is accurate to .1 or .01 ... **
d; the more decimal places the more accurate your answer is.
