** Your average time interval for 20 time intervals **
.203
I got this answer by adding all times and dividing by 20.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.15625, 6
.171875, 9
.1875, 3
.203125, 1
** Your general comment to this point **
** Why did you observe only certain time intervals? **
I think the program can only measure times to a certain accuracy, then just gives an approximate time when it can't give the exact time.
** What did you see when you looked at the differences between time successive time intervals? **
The program is accurate to +0.03125 and -0.01563
** Your time intervals for 7 complete breaths: **
10.10938
16.73438
22.60938
28.3125
34.48438
41.10938
46.8125
53.70313
59.375
65.1875
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
Because the time interval increased greatly timing breaths, instead of the fast clicks.
** Do you think this program is accurate to .1 or .01 ... **
a.
This is because the numbers tend to repeat after measuring .1 second.
