** Your General Comment **

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

I see 10 rows with two columns each. Each of the columns has a recorded time.

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

12.308

I added each of the intervals and divided by 20 to get 12.308.

If you divide 246.16 by 20 you get 12.308. However 246.16 is the time that elapsed between opening the program and your first click. It has very little to do with the time intervals bewteen your clicks.

&#

Intervals are typically between .1 sec and .25 sec. Smaller intervals are sometimes observed between quick clicks--some people are just plain quick on this exercise. Intervals greater than .3 seconds or so are almost certainly not the result of 'quick clicks'; if you had intervals in this range within your sequence of clicks then you should have tried another sequence, until you could get 20 good clicks. While you do want to report the TIMER's complete output, you should not include in your analysis intervals that do not correspond to the quantity being observed.For example, you might well have something like 30 seconds, or more, between the time you started the program and the time you started your 'quick clicks'. You would not report that as one of your intervals. You might have a number of lapses between sequences of quick clicks, and you might have made an extra click after finishing the quick-click sequence. These long intervals would not be reported in your frequency distribution. &#

What therefore is the average of the time intervals between your clicks?

** Your general comment to this point **

So far, so good.

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

No the TIMER is not flawed or useless, once we figure out how the time intervals are calculated we will be able to use it more accurately.

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

I noticed that with the difference in time intervals, some of the times are repeated frequently as well. It seems like the timer program only gives approximate values or rough estimates of the time intervals.

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

5.164063

** Your general comment to this point: **

This trial seems to be more precise, no repeats.

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

In the first test, the TIMER program took a rough estimate of our clicks and rounded the times. It's almost as if it was anticipating when the clicks would occur and recording that time. In the second time with the relaxed breaths, there was more time between the clicks, thus the Timer program was able to get more accurate results.

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

THe answer is B-

Looking at the difference between time intervals they are all accurate to within about .01 seconds. There were no measurements taken that were more precise.
