Graphs How to set up successful graphs

How to set up your graph!

Y Axis (This is for your dependent variable)

How to set up your graph! X Axis (This is for your independent variable)

TAILS T T – Title Choose a descriptive title that explains what is being measured in the graph Teachers’s Favorite Singer

TAILS T - T - Title A - Axis Teachers’s Favorite Singer Y Axis = Dependent Variable X Axis = Independent Variable

TAILS T - T - Title A – Axis S – Scale Teachers’s Favorite Singer Decide on an appropriate scale for each axis. Choose a scale that lets you make the graph as large as possible for your paper and data

How to determine scale Scale is determined by your highest & lowest number. In this case your scale would be from 2 – 22. Favorite Singer Number of Teachers Brad Paisley22 Bruce Springsteen 15 Eddie Vedder 11 Sting5 Sinatra2

TAILS T – Title A – Axis I – Interval S – Scale Teachers’s Favorite Singer The amount of space between one number and the next or one type of data and the next on the graph. The interval is just as important as the scale Choose an interval that lets you make the graph as large as possible for your paper and data

How to determine Intervals The interval is decided by your scale. In this case your scale would be from 2 – 22 and you want the scale to fit the graph. The best interval would be to go by 5’s. Favorite Singer Number of Teachers Brad Paisley22 Bruce Springsteen 15 Eddie Vedder 11 Sting5 Sinatra2

TAILS T – Title A – Axis I – Interval S – Scale Teachers’s Favorite Singer

TAILS T – Title A – Axis I – Interval L – Labels S – Scale Teachers’s Favorite Singer Brad Pasiley Bruce Springsteen Eddie Vedder Sting Sinatra LABEL your axis or data points Singers Give the axis a general label. What do those words mean? Number of Teachers Label your Y Axis. What do those numbers mean?

When to use… Bar graphsBar graphs –Used to show data that are not continuous. –Allows us to compare data like amounts or frequency or categories –Allow us to make generalizations about the data –Help us see differences in data Line GraphsLine Graphs –For continuous data –useful for showing trends over time

Graphing Motion Line graphs In a distance time graph, the distance of an object is plotted along the y-axis and the time along the x-axis.

Label each axis Time Distance

Graphing Motion

Motion Graph # 1 Straight, Flat Line As time passes, there is no change in distance; no motion

Motion Graph # 2 Straight, Increasing Line As time passes, distance increases The change in distance is constant – no stopping & starting

Motion Graph # 3 Straight, Decreasing Line As time passes, distance decreases The change in distance is constant

Motion Graph # 4 Changing Line A changing line means changing distance Distance increases  doesn’t change  distance decreases

Graphing acceleration Acceleration is always shown as a curved line
