** Your average time interval for 20 time intervals **
0.1742
I subtracted the total time in #20 from the initial time in #1 and divided by 20.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.15625, 3
.171875, 8
.1875, 5
.203125, 2
.296875, 1
** Your general comment to this point **
** Why did you observe only certain time intervals? **
It measures an average to the nearest .000250.
** What did you see when you looked at the differences between time successive time intervals? **
I see .01563, .015625, and .03152 as the common numbers. This tells me that the timer is only accurate to the hundredths.
** Your time intervals for 7 complete breaths: **
5.390625
8.65625
9.78125
11.51563
12.10938
14.09375
15.26563
15.26563
15.29688
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
Because there were much longer intervals occuring, so the chances of intervals being exact decreases.
** Do you think this program is accurate to .1 or .01 ... **

I followed the directions just as you have them typed to save in Excel, but it still didn't come up correctly.
