** Your average time interval for 20 time intervals **
.1709
i got the avg by subtracting the first clock timer from the 20th and then dividing by 20
'Good, except that there are only 19 intervals in your 20 clicks.
'Alternatively you could have added the intervals in your third column and divided the number of intervals.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.140625, 4
.15625, 3
.171875, 4
.1875, 2
.23235, 1
.2825,1
.30285, 1
** Your general comment to this point **
** Why did you observe only certain time intervals? **
i don't think it's as accurate as that. the program must run on approximates. it is not useless, just not exact, much like us
** What did you see when you looked at the differences between time successive time intervals? **
the last numbers are rounded off to however the timer program must have been programmed, not accurate past the hundreth place
** Your time intervals for 7 complete breaths: **
1 1806.641
2 1808.609
3 1811.609
4 1814.828
5 1818.125
6 1821.094
7 1824.594
8 1828.688
9 1831.813
10 1834.813
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
the likelihood of us hitting the exact same time is reduced greatly as we took longer intervals between clicks
** Do you think this program is accurate to .1 or .01 ... **
B is accurate because after the hundreths place, the program seemed to repeat and be rounded off.
