** Your General Comment **
I already submitted this assignment once but think I forgot to enter my access code so I repeated the exp. here
** Describe what you see on your first 10 clicks **
3 cols of numbers, The first is a col of increasing integers starting with 1. The second seems to be a timer from the moment the program was initiated with an entry at each mouse click. The third seems to be intervals between mouse clicks
** Your TIMER data from 20 fast clicks **

** Your average time interval for 20 time intervals **
.182813
I copied the results into excel, removed the extraneous data then applied a formula to average
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
0.15625, 2
0.17185, 6
0.1875, 9
0.203125, 2
0.21875, 1
** Your general comment to this point **
** Why did you observe only certain time intervals? **
It would seem that the timer is only capable of recording intervals at given intervals. Apparently 1/64 sec.
** What did you see when you looked at the differences between time successive time intervals? **
A repeating pattern of numbers all evenly divisible by 1/64
** Your time intervals for 7 complete breaths: **
2.984375
2.921875
2.84375
2.890625
2.53125
2.578125
2.65625
2.9375
2.8125
2.96875
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
The timer program is accurate to 1/64 sec but our human ability is not that precise
** Do you think this program is accurate to .1 or .01 ... **
d
The program is capable but the human interface is limiting
** Copy of a few lines of your spreadsheet from the TIMER program. **
