** #$&*Your average time interval for 20 time intervals **
.183547
I added the first 20 intervals and divided the answer by 20.
** #$&*Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.1640625, 1
.171875, 6
.1796875, 2
.1875, 8
.203125, 3
** #$&*Your general comment to this point **
** #$&*Why did you observe only certain time intervals? **
My guess would be that the timer program has a number of anticipated intervals that it uses to measure the space between clicks. I would think that it uses the one closest to the actual click.
** #$&*What did you see when you looked at the differences between time successive time intervals? **
There are both positive and negative numbers present in the new column, and they vary. These numbers tell me that the time program is fairly accurate, because the differences keep changing, so the program recognizes that the intervals are not exactly consistent.
** #$&*Your time intervals for 7 complete breaths: **
6.164063
6.125
5.320313
6.289063
5.429688
5.835938
6.0625
6.429688
6.257813
5.898438
** #$&*Your general comment to this point: **
** #$&*Why did you rarely, if ever, observe that same time interval twice? **
The time internval between the clicks/breaths in this case is much longer. To click on the exact same interval would be nearly impossible.
** #$&*Do you think this program is accurate to .1 or .01 ... **
d. Looking at the time intervals of the first data tables, the program can still differentiate between clicks at these intervals.
** #$&*Copy of a few lines of your spreadsheet from the TIMER program. **
