Mr. Smith, What does this statemnt mean? Determine the square root of the mean of the squared distances from the mean position. I am not sure where to start working on that.

If we deconstruct the phrases we find that they say to

square the distances from the mean position find the mean of those squared distances (add up the squared distances then divide by n) take the square root of that result

We will of course go over this in class tomorrow.

Have you happened to have a chance to grade my test.

Your test is graded and the grade is posted.
