### GRAPH RUBRICworth 4 points

• 1 pt – Title

• 1 pt – Labels with UnitsIV on X-axis & DV on Y-axis

• 1 pt – Consistent Numbering / Naming

• 1 pt – Correct line / bars

based on IV and Averages

### GRAPH FORMAT

The effect of “IV” on “DV”

DV (units)

IV (units)

• Bar Graph

• Line Graph

### BAR GRAPH

• For when the IV is quaLitative

• example

### LINE GRAPH

• For when the IV is quaNtitative

• example

### Skeleton graph

• No data input. Just title and labels

• The same for each type of graph

• example

• What type of graph do we use for a qualitative IV?

• What type of graph do we use for a quantitative IV?
