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

4.8390625

Well, I did the hard way by adding the 20 numbers and dividing by 20 however I transferred them to Excel and did the sum there.

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

0.1875,4

0.140625,3

0.171875,5

0.15625,7

** Your general comment to this point **

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

No, it timed the amount of time it took me to click the mouse each time.

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

The difference is consistent, almost has a pattern to it. This tells me that the timer program picks up on the pattern of my clicking the counter.

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

1089.047

2.4375

2.390625

1.875

1.65625

1.96875

2.296875

1.6875

1.671875

1.796875

** Your general comment to this point: **

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

Because there is not a patter to our breathing.

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