1. X- Axis = Independent variable If time is present, it is usually ALWAYS goes on the x-axis (independent variable) If time is present, it is usually ALWAYS goes on the x-axis (independent variable) Y- Axis = Dependent variable

2. T.A.I.L.S for graphs T = Title is present A = Correctly label x/y-axes (with label & units) I = Use consistent intervals on axes-space intervals evenly (intervals do not need to be the same on each axis) L = Label a key (if applicable) S = Size (BIG graphs/use entire graph paper)

3. Line graph vs. Bar graph When the independent variable has: – only certain fixed values, use a bar- graph. – A continuous range of values, use a line-graph.

4. Example: Number of birds chirping in the morning during the different temperatures of the year. Temperature (°C) 2046308 Number of birds chirping 141245

5. Bar graph example: Number of Lane tech students in each grade: Number of students 105010051100950 GradeFreshmenSophomoresJuniorsSeniors
