** Your general comment to this point **
** Why did you observe only certain time intervals? **
No, having a larger variation in the numbers would infact be less usefull. It would never suggest any pattern or relationship between the timer intervals. By approximating, we can began to establish patterns.
** What did you see when you looked at the differences between time successive time intervals? **
intervals are rounded to the hundrenth of a second.
** Your time intervals for 7 complete breaths: **
4.742188
4.992188
5.101563
5.1875
5.023438
4.875

** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
The actual time that one takes in a breath and the delay between actually selecting the record button, allows for additional time delay and error. Which is translated within the interval records.
** Do you think this program is accurate to .1 or .01 ... **
b. Based on the aforementioned supporting data logs, one should interpelate that timer accuracy is to one one-hundreth of a second.
** Copy of a few lines of your spreadsheet from the TIMER program. **

Not exactly sure. Perhaps 40 minutes.

It doesn't appear that you were clicking as fast as possible on the first set of data; also the data requested includes 20 intervals. As a result you didn't get a frequency distribution.
You should repeat the exercise, make sure the clicks are as fast as possible, and give the frequency distribution.
Also be sure to include your name so I know whose work I'm reviewing.
