I see the time that it started to count and the change in time between each time I click the button.

** Your average time interval for 20 time intervals **
.08671875 .1171875
For the first set of numbers I just added up the numbers and divided by 20. However, I did try adding the largest answer by the smallest answer and I divided that by 2, but the answer I got just seemed way too large.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.140625, 1
.125, 1
.109375, 13
.09375, 5
** Your general comment to this point **
What is the easier way for finding the average change in time that you mentioned earlier?
** Why did you observe only certain time intervals? **
No, It just means that decimal changes are extremely small and just can't be detected by the timer. So it just your too fast for the clock.
** What did you see when you looked at the differences between time successive time intervals? **
The numbers in the last column are telling you the the change in the between the changes of the time intervals and whether the changes are faster or slower, positive or negative.
** Your time intervals for 7 complete breaths: **
2.453125
8.015625
13.45313
18.95313
24.375
29.79688
35.17188
41.34375
47.01563
52.4375
** Your general comment to this point: **
No comment
** Why did you rarely, if ever, observe that same time interval twice? **
because we aren't trying to go as fast as we can. We are controlling the speed of our breathes and we are able to get a more reasonable time out of it.
** Do you think this program is accurate to .1 or .01 ... **
b. The TIMER program is capable of determining the time between two events accurately to within about .01 second

about an hour and a half, but I was distracted by the television.
