** 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. **
