** Describe what you see on your first 10 clicks **
Each time I click the Click to Time Event button there is a table that appears that looks like this:
1 13.6875 13.6875

3 15.20313 .578125

** Your general comment to this point **
What does each column of numbers stand for, and what does the number in the top white box mean?
** Why did you observe only certain time intervals? **
This does not at all mean that the TIMER program is flawed or useless. I would conclude that the TIMER program reports this times most frequently because when is trying to click the mouse as fast as he/she can the program can not possibly register each individual click. Therefore, three or four fast clicks results in a single time. When considering this flaw into our calculations, we must also calculate a degree of percent error.
** What did you see when you looked at the differences between time successive time intervals? **
With the exception of a couple of intervals, there is not much of a difference from one time interval to the next which can mean one of two things. Either the TIMER program is really good at measuring the consistency of human coordination in clicking the mouse, or we are clicking so fast that it cannot possibly measure each click as accurately as we would like for it to. The most likely possibility is the latter of the two solutions mentioned.
** Your time intervals for 7 complete breaths: **
5.59375
5.234375
6.34375
4.9375
5.734375
5.34375
4.859375
5.75
5.203125
7.1875
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
Because the computer is not trying to interpret large amount of input data from multiple fast mouse clicks, it is instead interpreting individual clicks over spaced intervals of time which results in more accurate data.
** Do you think this program is accurate to .1 or .01 ... **
I think statement A is the most accurate. If you run this TIMER program using in your own opinion what you consider to be fast, medium, and slow clicking patterns, as the speed of the click increases the less accurate the results become. Therefore, because .1 is the largest of the accuracy rates we can choose from I chose that one.
