** Your average time interval for 20 time intervals **
0.15481
I averaged the number together and didvided by 20.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.15625, 2
.1523438, 8
.1640625, 5
.1445313, 2
** Your general comment to this point **
** Why did you observe only certain time intervals? **
I really don't understand the frequency because after looking at my numbers I thought I was more accurate than I was. I think that the timer is so accurate that no matter what you would never be able to get a equal time between intervals. I don't beleive that the program is flawed or useless.
** What did you see when you looked at the differences between time successive time intervals? **
It tells me that the timer is very extensive and accurate. I also see alot of the same numbers.
** Your time intervals for 7 complete breaths: **
2.394531
2.015625
1.796875
2.070313
1.984375
1.90625
1.859375
2.035156
1.90625
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
The fast clicks were completed in a certain form. Click after click. The breathing one was more spread out, it was not evenly done because the breaths are not even and reaction is slower.
** Do you think this program is accurate to .1 or .01 ... **
b. because the numbers when you look down the line start to change in the .01 space.
** Copy of a few lines of your spreadsheet from the TIMER program. **
