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

TAILS Teachers’s Favorite Singer T - Title

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

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 Scale is determined by your highest & lowest number. Toby Keith 22 In this case your scale would be from 2 – 22. Madonna 15 Elvis 11 Sting 5 Sinatra 2

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.

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

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