** Your General Comment **

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

the numbered intervals and times in order, i noticed the time starts when the program is opened and not when the button is first clicked. I'm not sure if this is correct but that seems to be the case.

It does that, so the first interval usually has to be disregarded (as you have done).

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

.09356

I subtracted the first number in the second column from the last number in the second column to find the derivative, then divided by 20.

** Your general comment to this point **

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

no, it must round up or down because all of my intervals ended in a 5 as well.

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

tells us how far off each time interval is from the previous one

** Your general comment to this point: **

I just relaxed and breathed normally instead of taking deep breaths.

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

the greater the interval, the more room for error or difference in each interval.

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

D. .0001 seconds, based on the difference from one time interval to the next
