** Your General Comment **
** Describe what you see on your first 10 clicks **
The first column has the time on the clock and the second column is the time between each click.

** Your average time interval for 20 time intervals **
0.158595
I took the first time on the clock and subtracted it from the last time on the clock and divided it by 20 to get the average amount the clock went up each time.
Good, except that there are only 19 intervals in your 20 clicks.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.140625, 3
.15625, 11
.171875, 6
** Your general comment to this point **
** Why did you observe only certain time intervals? **
The timer program is not flawed and is not useless, it is probably set to give times in a certain number of decimal places.
** What did you see when you looked at the differences between time successive time intervals? **
The interval -0.01563 occurs the most, which probably means thats the lowest number the TIMER program goes to.
** Your time intervals for 7 complete breaths: **
3.84375
3.984375
4.5
4.5625
4.5625
4.765625
4.875
5.078125
5.203125
5.4375
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
The same time intervals did not happen as often because I wasn't clicking as fast and the time intervals were longer when clicking only when I inhaled.
** Do you think this program is accurate to .1 or .01 ... **
b, because the differences in the time intervals were all .0... For example: .03, .05, etc
** Copy of a few lines of your spreadsheet from the TIMER program. **
