** Your General Comment **
** Describe what you see on your first 10 clicks **
I see a list of numbers numbered 1 thru 10 with times next to them. It is the amount of time between when I clicked the mouse.

** Your average time interval for 20 time intervals **
.204023445
I don't know how to do it the easy way so I added up the numbers and then divided them by 20 to get the average
you could also subtract the first clock time from the 20th and divide by 20, but the way you did it is also fine
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.140625, 2

.1679688, 1
.171875, 7
.1835938, 1
.1875, 5

** Your general comment to this point **
** Why did you observe only certain time intervals? **
It is useful for an estimated time amount. Does not calculate the exact amount but an amount that is close.
** What did you see when you looked at the differences between time successive time intervals? **
When time is passing so fast the timer program tracks it in close sequences. During all the times the program ends with a 63 or a 25 which makes a lot of the numbers come out the same. It approximates the times.
** Your time intervals for 7 complete breaths: **
6.414063
5.503906
5.742188
5.972656
3.242188
6.472656
6.179688
5.925781
7.050781
4.183594
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
Because when you move slower the program has time to keep up so you would have different results every time.
** Do you think this program is accurate to .1 or .01 ... **
I think that the answer is c. the timer program is capable of determining the time between two events accurately within about.001 seconds.
** Copy of a few lines of your spreadsheet from the TIMER program. **
I only have a trial version of excel since I had to purchase a new computer and cannot copy any information from my excel yet

You did well on this experiment.
