Your average time interval for 20 time intervals

.46171875

The 6.24 second interval should not have been included. The instructions indicated that you should time 20 quick intervals. 6.1 seconds was not a quick interval. However you method of finding the average is valid and if the 6.14-second interval is included you your average appears correct.

I took the number right beside the 20th time number which was 9.234375 and divided it by 20.

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 would not think it is flawed it is just the reaction your brain to your finger tips on the mouse.

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

Some of the numbers are negatives and it represents the time from each click. It is showing how you slowed down and sped up.

Your time intervals for 7 complete breaths:

3.171875

3.578125

3.625

4.09375

4.171875

4.84375

25.20313

While you might well have taken 25.2 seconds between your last two breaths, this result appears inconsistent with the others and I have to question it.

Your general comment to this point:

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

Your breathing and clicking is not going to be the same.

Do you think this program is accurate to .1 or .01 ...

a. The TIMER program is capable of determining the time between two events accurately to within about .1 second.

You are using the program correctly. A couple of questions arise regarding a couple of your reported data points, but no serious problem. Be sure, however, to see my notes.
