Your 'timer program' report has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.
** Your General Comment **
** Describe what you see on your first 10 clicks **
I see the timer numbers for each time I clicked the mouse. This is similar to what I did in Physics with the timer program
** Your TIMER data from 20 fast clicks **

** Your average time interval for 20 time intervals **
.20135
I looked at the numbers and I saw the number in line one of which I saw 10 of these numbers so I thought that would be a consistent number because of the inconsistency of clicking the mouse
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.15625, 1
.171875, 2
.1875, 3
.203125, 11
.21875, 3
** Your general comment to this point **
About the same thoughts from 1st semester
** Why did you observe only certain time intervals? **
It has something to do with the computer timing and counting sequence.
** What did you see when you looked at the differences between time successive time intervals? **
The last column indicates the difference from the time on the same line and the next line. Unfortunately this doesn't show on my timer program and doesn't show on a newly downloaded program
** Your time intervals for 7 complete breaths: **
1 1060.234
2 1062.875
3 1066
4 1069.391
5 1072.625
6 1076.078
7 1079.141
8 1082.609
9 1085.859
10 1089.203
11 1092.016
** Your general comment to this point: **
It looks like I'm still alive!!!
You reported clock times, not time intervals. The intervals appear to average about 3 seconds.
That is, of course, a sure sign of life.
** Why did you rarely, if ever, observe that same time interval twice? **
When you are breathing you are timing yourself at specific time intervals which could be changing as you operate the program and clicking the mouse with you finger.
** Do you think this program is accurate to .1 or .01 ... **
I kind of looks as if the timer program can do the accuracy to .1 seconds but I think it can do a little bit better if timing events other than breathing.
** Copy of a few lines of your spreadsheet from the TIMER program. **
I did exactly what was requested and the files wasn't saved to Excel. I know it is saved somewhere in a Physics 202 folder named breathing and exhalation in my documents as I did last semester. So I guess I need some different instructions on how to get this to the excel spreadsheet.

Probably about 30 minutes because of having used the timer program before. Previously I had a hard time getting the timer program to work then I downloaded the compound 32 or something like that and the program worked.

Also the timer program I'm running doesn't display the third column does that mean that I have the wrong program. I just redownloaded the program but nothing has changed
Your report of the fast clicks did include the third column. I can't think of a reason the third column wouldn't be there.
You don't actually use the TIMER a whole lot in this course, so I don't think this will be a problem.
Note that you aren't required to repeat experiments you did first semester. It never hurts to refresh, but you've certainly paid your dues.
