** Your General Comment **
** Describe what you see on your first 10 clicks **
I see a chart with two sets of numbers, i guess the first column is the time since i opened the program, and the second value is the time interval between clicks.

** Your average time interval for 20 time intervals **
.1812
I subtracted the first number from the last number and divided by the number of values to get the average.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.15625, 1
.171875, 1
.1835938, 1
.1875, 5
.203125, 1
** Your general comment to this point **
** Why did you observe only certain time intervals? **
I think the computer program rounded up when it was close to .1875 because it is a nice even number, 3/16ths.
** What did you see when you looked at the differences between time successive time intervals? **
the numbers are both positive and negative, so it is showing whether the value is more or less than the last recorded interval.

** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
Because you get in a rhythm clicking on fast clicks.
** Do you think this program is accurate to .1 or .01 ... **
B. The TIMER program is capable of determining the time between two events accurately to within about .01 second.
