Your average time interval for 20 time intervals

0.21328125

I did (5.75-1.484375)/20 to get the above answer.

Your frequency distribution for the 20 time intervals (interval, number of times it was observed)

Your general comment to this point

Why did you observe only certain time intervals?

I think that it has something to do with the computer. I don't think that the TIMER program is flawed and I still think that it's very helpful.

What did you see when you looked at the differences between time successive time intervals?

That the difference from one time inerval to the next is often the same so it causes repitition in the time interval.

Your general comment to this point:

Why did you rarely, if ever, observe that same time interval twice?

Because the longer the period between clicks the more numbers it could possibly be.

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 think that this is the correct answer because most of the time intervals go to at least the thoundsenths place.

Copy of a few lines of your spreadsheet from the TIMER program.

It came up with a message that said This version of the Timer won't file. Try copying and pasting the display.
