** Describe what you see on your first 10 clicks **
It gives a list of numbers in the first column and then what looks like the difference between each interval in the second column.

** Your average time interval for 20 time intervals **
.10820267
I got the average by adding up the first 20 time intervals and then dividing by 20.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.089843, 4
.09675, 1
.1015625, 1
.109375, 9
.1132813, 3
.140625, 2
** Your general comment to this point **
** Why did you observe only certain time intervals? **
I don't think that the timer program is useless. However, on your results as well as mine the majority of the intervals ended with a .xxxx5. Therefore, this might be a flaw in the timer when going at such a rapid pace. Maybe at a slower pace, the timer will have time to pick up on other decimals besides 5.
** What did you see when you looked at the differences between time successive time intervals? **
A lot of the numbers in the last column are almost the exact same and many of them are. The timer program seems to give a lot of the same numbers. Again, this may be because we are going at such a fast pace and the program can't keep up.

&#These are clock times, not intervals. The TIMER program shows three columns. It numbers the clock times in the first column (1, 2, 3, 4, ...), gives clock times is the second column and the intervals between clock times in the third. Be sure you distinguish between clock times and time intervals. &#
** Your general comment to this point: **
I don't know why your intervals are starting with numbers like 17, 18, and 21 and mine are starting with numbers in the thousands like 1280, 1285, and 1289.
** Why did you rarely, if ever, observe that same time interval twice? **
I think the breathing results are more accurate because we were going at a slower pace and allowing the time time to catch up and get a more accurate measurement.
** Do you think this program is accurate to .1 or .01 ... **
I think the answer is (a) because when I did the first experiment with the clicks I seemed to get a lot more rounded answers and a lot of these ended in 5. However, when I did the breathing exercise the numbers seemed to be a lot more accurate to the very last decimal point.

&#Good responses but be sure you remain aware of the distinction between clock times and time intervals.
