** Your average time interval for 20 time intervals **
Avg. Interval - .14141
I attained this by finding the interval from the first to the twentieth click and dividing it by 20.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
0625, 1
.109375, 7
.125, 6

.21875, 1

** Your general comment to this point **
** Why did you observe only certain time intervals? **
This is an interesting question because I was wondering the same thing. It looks like the program records time at intervals of .000125 so the results are probably rounded. However, the actual times are much more random. This doesnt mean that the program is useless because in experiments it is desirable to have systematic results.
** What did you see when you looked at the differences between time successive time intervals? **
The program enures that the deviation of the interval stays systematic. So if we were trying to create an experiment with regular time intervals we can do so without having to do it manually.
** Your time intervals for 7 complete breaths: **
7.4375
6.1875
5.453125
6.1875
7.015625
7.46875
6.34375
6.765625
6.578125
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
Since the intervals are larger than before, the field of possibilites becomes alot larger for each interval. This time, I only had two intervals which were the same.
** Do you think this program is accurate to .1 or .01 ... **
d) the intervals recorded are rounded after going past .0001
