graphing general rules enviro

where does the independent variable go

on the X- axis (horizontal)

where does the depenent variable go

on the Y-axis (verticle)

both axis must be fully labeled with

description and units

when do you use a line graph

• graph when independent varaible (IV) is continous variable

• time

• light intensity

• DO levels

• CO2 concentration

• PH levels

when do you use a bar graph (spaces)

when independent varaible (IV) is a discontinous varaible

• categories

• group of organisms

• different locations

histogram (no spaces)

when independent variables is continous but shows range

• data is colleted 0-5, 10-15 away from the low water mark

what is DRY MIX

• depdent varaible

• respdonging variable

• Y- axis

• —-

• Manipulated variable

• independent varaible

• X-axis
