### Elijah's scribe post for September 24, 2009

Question 7.

The table shows the heights of two friends measured over time.

(a) Use a double bar graph and a double line graph to display the data.

Double Bar graph :

Double Line graph:

(b) How are the trends for Andrea and Lewis similar? How are they different ?
Andrea and Lewis's trends are similar until age 2-10 where, Andrea was taller than Lewis. But it then changes by age 12-16 because, Lewis is taller than Andrea.

(c) Which graph do you think more clearly shows each student's height trend? Explain your choice.
The line graph shows the students height trends, because line graphs are better for things that change over time.

(d) Would two circle graphs be effective for displaying the data? Explain why or why not .
Two circle graphs wont be as effetive because there was no total given.
