** Describe what you see on your first 10 clicks **

I see a column listing numbers ranging between 72.98438 & 74.76563, and also some entries beside them (can't figure out the connection between them, though)

** Your average time interval for 20 time intervals **

.176809

&#If you divide the difference between the 1st and 20th time clock times by the 20 - 1 = 19 time intervals you would get the average time interval, and this will agree with the average you obtained by adding the 19 intervals and dividing by 19.

More generally, if you take the difference between two clock times and the difference between their numberings, i.e., subtract the second-column numbers, subtract the first-column numbers and divide, you will get the average of the time intervals between those clock times. &#

** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **

.15625, 5

.1875, 5

.171875, 8

.265625, 1

** Your general comment to this point **

.

** Why did you observe only certain time intervals? **

no

** What did you see when you looked at the differences between time successive time intervals? **

The time intervals listed above match what I came up with in the exercise; the TIMER program is very accurate.

** Your time intervals for 7 complete breaths: **

3.93

4.140625

4.203125

4.921875

4.953125

5.078125

4.625

** Your general comment to this point: **

hope I did that last exercise right

** Why did you rarely, if ever, observe that same time interval twice? **

Good question--I don't know

** Do you think this program is accurate to .1 or .01 ... **

I'll guess letter C, since numbers from .0001 second and quicker seem to be arranged more randomly in the sequence, i.e., less accurate (?)

** Copy of a few lines of your spreadsheet from the TIMER program. **
