662 660 658 656 | 654 S 652 650 648 10 20 30 adings 40 50 Number of re Figure 1-Graph of running average of the Range, R, for a ball "projectile" released from the same height Therefore, when you see a dispersion, a.k.a. a "scatter" in your readings in an experiment, then you should try to take as many readings as possible. Of course, it is ustually not practical to take millions of readings, but you need to carefully consider how many repeated readings are necessary to give a reliable average. Question 3-By looking at Figure 1, above, decide how many rolls of the ball from this same height would be reasonable to give a reliable average for the range? Can you justify your answer?

Explanation / Answer

I think for this measurement 35-40 number of reading is sufficient. Because as you can see that after this the reading more or less saturates.That's why I choose 35-40 number of reading.
