4.1 Think about this question: If you know the measure of a person's arm span, do you know anything about his or her height?

4.1 To help answer this question, you will need to collect some data. With your class, collect the height and arm span of each person in your class. Make a coordinate graph of your data. Then, use your graph to answer the question above.



4.1 No because height of a person is very different than the arm span of a person. Height is vertical and arm span is horizontal... so you wouldn't know anything about his or her height if you know the arm span.

4.1 Follow Up

Draw a diagonal line through the points on the graph where the measures for arm span and height are the same.



4.1 F.U

1. How many of your classmates' data are on this line? What is true about arm span compared to height for the points on this line?

No one has the same height and arm span. There are some people who almost do... but not the exact same height and arm span. I can't answer this question: What is true about arm span compared to height for the points on this line? Because there is nobody on the line.

2. What is true about arm span compared to height for the points //below// the line you drew?

It means that you have arms that are longer than your height.

3. What is rue about arm span compared to height for the points //above// the line you drew?

It means your height is longer than your arm span.
