## Graphing Basics

### Creating a graph

Draw the y-axis on the

vertical axis and the

X-axis on the horizontal

one

Label what variable is on each of the axis and show units

Title graph using format y vs. x

Distance vs. Time

Distance (m)

Time (s)

Decide on what intervals you will be using

on each axis and write those in

• Be sure that the intervals are even and appropriate to the measurements you have taken

John’s Weight vs. Year

Plot the data points that you collected on the graph (Scatter plot)

Draw the line of best fit(trend line)  A line on a scatter plot which can be drawn near the points to more clearly show the trend between two sets of data.
