What types of graphs are best suited to showing measurements of the following (6 DIFFEREN STATTIONS) :

- acidity (3 seperate measurements at each station)

- dissolved oxygen (1 measurement at each station)

- Biochemical Oxygen Demand (measurement at each station)

- Total Dissolved Solids (Initial results given)

- AAS Metal ion Analysis (Standard solutions of Pb, Zn, and Cu are given, as well as the absorbance at each site)

arghh.. i need some assistence plz !

For AAS metal ion analysis, you would use a calibration curve (line of best fit) for each metal ion. Put the independent variable (concentration of the ion) on the horizontal axis and the dependent variable (absorbance) on the vertical axis. I'm not sure about any of the others. Hope that helps.
