__Problem 4.1. Collect the height and arm span of each member of your class. With your data, make a coordinate graph. Use your graph to answer the question "If you know the measure of a person's arm span, do you know anything about his or her height?".__ Table of Arm Span vs. Height You cannot determine the height of someone by his or her arm span because the height doesn't affect his or her arm span. He or she could have been really short but have long arms or be really tall but have short arms. It could be the other way around, also. He or she could have been short and have short arms or be tall and have long arms.

__Problem 4.1 Follow Up. Where the arm span length and the height are the same, draw a diagonal line through those points.__ __1. How many of your classmates' data points are on this line? What is correct for arm span compared to height for the points on this line?__ No one in my class's data points are on this line. If there is a point on this line, it means that their height and their arm span are the same. But in my class no one's arm span and height are the same, because no data points are on this line. __2. What is correct for arm span compared to height for the data points under this line?__ If someone's data point is under this line, that means that their arm span is longer than their height. They are short but their arms are long. __3. What is correct for arm span compared to height for the data points above this line?__ If someone's data point is above this line, that means that their arm span is shorter than their height. They are tall but their arms are short.
