Describe what you see on your first 10 clicks
I see three columns. One with the number of times I have clicked the time event, one column with numbers from 23 to 25 with four decimal places, and one column with numbers less than 1.

Your average time interval for 20 time intervals

I just added the interval and divided by 23.
Your frequency distribution for the 20 time intervals (interval, number of times it was observed)
.140625, 9
.125, 5
.28125, 1
.4375, 1
.109365, 2
.25, 1

Your general comment to this point
I'm not too sure where this is going, because my most frequent number is not THAT close to my average.
Why did you observe only certain time intervals?
No, I think the TIMER program was simply rounding the time. The program is not useless, just not precise.
What did you see when you looked at the differences between time successive time intervals?
I see negative numbers. I think the negative numbers show which direction (to the right or to the left) whatever is being timed is going. I think the negaive numbers show something going to the left in a certain time.

Your general comment to this point:
Why did you rarely, if ever, observe that same time interval twice?
I think this happend because no two intervals were the same. When we clicked the first time, the 20 fast clicks, we noticed many numbers were the same. But when there was more time between, the numbers were more spaced out and not the same. I think the TIMER program is more accurate when readings are spaced out.
Do you think this program is accurate to .1 or .01 ...
I think answer C, the TIMER program is capable of determining the time between two events accurately to within about .001 seconds. I think this because on my first set of data, the most frequent numbers were found when the decimal had more numbers.
