Due Date: November 10, 2010 Making Graphs using Technology: Data About Us Problem 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? To help you answer this question, you will need to 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. My Own Words: do i know a person's height if i know the person's arm span? Answer: Yes, because some people are perfect and some people are close to being perfect, and by being meaning perfect is there arm span and there height are the SAME. so yes you do know a little bit about there height if you know there arm span, and you do know a little bit about there arm span if you know about there height.! Problem 4.1 Follow Up: Draw a diagonal line though the points on the graph where the measure for the arm span and the height are the same. 1) How many of your classmates' data were on the line? What is true about arm span compared to height for the points on this line? Answer: As i said the people on the line is the person who is perfect! it means the there arm span and there height are the same, Also there is no one in my class who is on the line! 2) What is true about arm span compared to height for the points BELOW the line you drew? Answer: it means that there arms span are longer the there height, so they would look like monkeys. 3) What is true about arm span compared to height for the points ABOVE the line you drew? Answer:it means that there height is taller then there arm spans so they don't look like monkeys! Problem 4.1 follow up:
