Question 1- Answer question 4.1 and its follow up, and make a digital graph about our class's height vs arm span using http://www.shodor.org/interactivate/activities/ScatterPlot/

=Height vs Arm span =



Problem 4.1- If you know anything about the person's arm span, do you know anything about his or her height?

A- No, because even if you know someone's arm span, the height might be shorter or longer than the arm span. Maybe you can guess a little bit because the arm span and the height are similar, but most of the time, it will be hard to figure out a person's height by only using that person's arm span.

Problem 4.1 and it's follow up- 1. 2 students date are on the line. This tells us the students on the line are the students that has similar arm span and height. 2. For the students above the line, their arm span is more longer than their height. 3. For the students below the line, their height is more bigger than their arm span.
