Question

Data for Graph #2 A group of four students has been collecting data on the possible relationship between the age of a student in a particular Biology class and the grade they received. The students postulate that the older student, the better his or her grade will be. Here is their data: Age Sex Grade in the Biology Course 31 Female A 32 Male A 24 Female C 32 Male D 21 Female B 19 Female C 20 Male A 16 Male C 18 Female B 18 Male C 22 Female B 40 Male A 38 Male D 31 Female C 26 Female A 29 Male A 37 Male D 35 Male C 19 Female F 27 Female B 22 Male A 25 Female B 1. Plot the data so as to correlate it to their hypothesis. Is there a relationship between age and grade achieved in the class? If so, what is it? 2. Can all of the data fit in one graph? 3. Is some data irrelevant to the hypothesis being put forward or is all of it relevant? Explain your answer. 4. Could more than one graph be made from this data? Make at least one other graph that could be generated from this data.
