** Your General Comment **
** Describe what you see on your first 10 clicks **
The first line is an initial time, 18.71875 in both columns. The second through tenth lines, each column is a different number. The first column seems to be the next number that was on the timer when it was clicked, and the second column appears to be the difference between the current number and the number before, usually a small decimal number.

** Your average time interval for 20 time intervals **
0.1445312
I got this answer by subtracting the 20th click, 219.6875, by the 1st click, 216.9688, and then dividing the result by 20. I also added all of the time-intervals and divided by 20 in order to check my answer, and came up with the same result.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **

** Your general comment to this point **
** Why did you observe only certain time intervals? **
I think this TIMER program is just like any other program created by a human. There are things about every program that just arnt completly 100% accurate, including this program. Ithink that maybe this program might round the number, find a number close and just put the same number, or assume to a certain number that the human clicking the mouse is going to click the same many times.
** What did you see when you looked at the differences between time successive time intervals? **
I think program assumes a lot of the human controling it.
** Your time intervals for 7 complete breaths: **
4.28125
4.203125
3.84375
4.5625
4.375
3.984375
4.765625
3.734375
4.109375
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
Because the time between the clicks was much longer, giving more variation.
** Do you think this program is accurate to .1 or .01 ... **
A -- because the first test, with the fast clicks, shows that those values are not exactly accurate because the clicks were too fast.
** Copy of a few lines of your spreadsheet from the TIMER program. **
