Your general comment to this point

Why did you observe only certain time intervals?

The timer may round up.

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

The timer counts from when you did your time event.

Your general comment to this point:

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

Our body changes and we take breaths at different intervals. If we run, we take more breaths than if we were sleeping.

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

c

I had the exact same times during the breathing exercise. I don't think that my body is that accurate.

Your data look good, though it doesn't look like you used a run of 20 truly fast clicks for the first set.

After the due date we will be discussing this experiment further via an online forum.
