How to set up successful graphs

How to set up your graph!

(This is for your dependent variable) 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 Teachers’s Favorite Singer T - Title

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

Decide on an appropriate scale for each axis. TAILS 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 T - Title A – Axis S – Scale

How to determine scale Favorite Singer Number of Teachers Toby Keith 22 Madonna 15 Elvis 11 Sting 5 Sinatra 2 Scale is determined by your highest & lowest number. In this case your scale would be from 2 – 22.

How to determine Intervals Favorite Singer Number of Teachers Toby Keith 22 Madonna 15 Elvis 11 Sting 5 Sinatra 2 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.

T – Title A – Axis I – Interval S – Scale TAILS 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 T – Title A – Axis I – Interval S – Scale

T – Title A – Axis I – Interval S – Scale TAILS Teachers’s Favorite Singer T – Title A – Axis I – Interval S – Scale 25 20 15 10 5

T – Title A – Axis I – Interval L – Labels S – Scale TAILS Teachers’s Favorite Singer T – Title A – Axis I – Interval L – Labels S – Scale 25 20 15 Number of Teachers 10 5 LABEL your bars or data points Toby Keith Madonna Elvis Sting Sinatra Singers Label your Y Axis. What do those numbers mean? Give the bars a general label. What do those words mean?

When to use… Bar graphs Line Graphs For continuous data 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 Graphs For continuous data useful for showing trends over time
