Your General Comment
I have received my CDs finally and will do my best to complete the overdue assignments as quickly as I can. I apologize for the delay.
Describe what you see on your first 10 clicks
I see the what I believe to be the time since I opened the program for the first entry. After that it appears as if the second column gives me split times since the last click.

I added up my first twenty intervals and divided by twenty to get my average.

Your general comment to this point
I don't understand yet what the faster averaging method was, but I'm thinking that is the point of this exercise, so I will be patient.
Why did you observe only certain time intervals?
The TIMER program probably averages the differences in the interval times to reach a consistent amount.
What did you see when you looked at the differences between time successive time intervals?
There seems to be a few set interval that a click can achieve. The different attempts by the human lead to a different click used by the program. It has a preset interval of time that can be achieved.

Your general comment to this point:
Why did you rarely, if ever, observe that same time interval twice?
The more time in between the clicks, the more set intervals there are for the program to record, and so there is a lower likelihood that the same interval will be achieved.
Do you think this program is accurate to .1 or .01 ...
c.
When the intervals are the same, they usually begin the same at the 0.001 level and not before. Rarely are they different any more accurate than that.

Good data.
After the due date we will be discussing this experiment further via an online forum.
