** Your General Comment **
** Describe what you see on your first 10 clicks **
I clicked the button 10 times and each time I click it, 2 different numbers appear to the right.
** Your TIMER data from 20 fast clicks **

** Your average time interval for 20 time intervals **
.1234375
I found the average by adding the first 20 times and dividing by 20.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.109375, 8
.125, 7
.140625, 4
.15625, 1
** Your general comment to this point **
** Why did you observe only certain time intervals? **
I believe the TIMER program is based on how fast the computer can comprehend a click of the click to time event, there are several programs running on a computer at one time and these programs require memory space, that's why it takes more time to comprehend the clicks than other times. I'm really just guessing here.
** What did you see when you looked at the differences between time successive time intervals? **
I see that the numbers are increasing then hit a peak and then go straight back down again. It does this several times. This data supports my reasoning about computer memory space.
** Your time intervals for 7 complete breaths: **
19.8125
16.32813
16.17188
17.15625
18.48438
19
20.46875
20.10938
22.3963
23.78125
** Your general comment to this point: **
My breathing was slowly becoming more relaxed and the time between my breaths kept increasing.
** Why did you rarely, if ever, observe that same time interval twice? **
I was becoming more and more relaxed so my breathing rate changed. The human body is not very predictable but a computer is.
** Do you think this program is accurate to .1 or .01 ... **
b, within .01 second because that was where the discrepency in numbers began when we clicked the button as fast we could.
** Copy of a few lines of your spreadsheet from the TIMER program. **

It took about 30m minutes to complete this assignment.

The above data from my spreadsheet is not the data that I obtained doing the breathing exercise. I accidently exited out of the program and lost that data.
Very good work. Let me know if you have questions.
