** #$&* Your General Comment **
** #$&* Describe what you see on your first 10 clicks **
I cannont open the timer.exe so I am using the timer-java. I see 4 colums. The first column has th enumbers 1-10 in it. The last column is a summary of the first 3 colums put together.

** #$&*Your average time interval for 20 time intervals **
0.1742
I added up all 20 intervals and divided the sum by 20.
Good, but note that .453 seconds does not correspond to an interval between quick clicks.
** #$&*Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.14, 1
.141,2
.156, 7
.157, 2
.171, 1
.172, 6
.453, 1
** #$&*Your general comment to this point **
** #$&*Why did you observe only certain time intervals? **
I got many of the same numbers multiple times too. I do not necessarily think that it is flawed.
** #$&*What did you see when you looked at the differences between time successive time intervals? **
The last column is the difference from one time interval to the next and has negative numbers in it. There are some times that are at least doubled which tells me that the person clicking the mouse was a little slower in clicking on a few of them.
** #$&*Your time intervals for 7 complete breaths: **
9.344
9.156
7.953
10.844
9.406
11.797
8.688
11.109
11.141
8.453
** #$&*Your general comment to this point: **
** #$&*Why did you rarely, if ever, observe that same time interval twice? **
When I was clicking the mouse it was at the fastest rate that I could go. Therefore since it was a fast controlled motion some of the same numbers appeared more than once. When breathing it is a slow and relaxing event where you are not thinking about time or as fast as you can breath
** #$&*Do you think this program is accurate to .1 or .01 ... **
c. The TIMER program is capable of determining the time between two events accurately to within about .001 second. I chose C because the numbers that it gives you are the same to the thousandth of a second which would make me think that it was accurate. However, it may be different with the other timer.
** #$&*Copy of a few lines of your spreadsheet from the TIMER program. **
I cannot get the timer to open and was not able to complete this part of the assignment

Is there any other way to open the timer.exe??? I tried both ways that you listed and am not having any success.
&#Very good responses. Let me know if you have questions. &#
