** Your average time interval for 20 time intervals **
.o78125
It is the mean of the 20 clicks.
You don't explain how you obtained this value for the mean. Please submit a copy of your data and an explanation of how you obtained the mean. I do not believe .078125 (which is indeed one of your time intervals) is the correct value for the mean. Submit your response using the title 'Timer Program: Calculation of the Mean'.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.109375, 3
.125, 3
.1484375, 2
** Your general comment to this point **
This is pointless thus far.
** Why did you observe only certain time intervals? **
The timer isn't flawed but it can't be 100% accurate. It is useful for the most part.
** What did you see when you looked at the differences between time successive time intervals? **
It repeats the same time intervals. The timer intervals are repetitive.
** Your time intervals for 7 complete breaths: **
3.554688
3.164063
3.070313
2.648438
2.359375
2.023438
2.3125
2.023438
1.585938
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
Because different people have different breathing habits.
** Do you think this program is accurate to .1 or .01 ... **
d.
Reasonable measurement between interavals for accuracy.

You are using the TIMER correctly, but you did not calculate the average time interval correctly. See my note and please respond as indicated.
