How to set up your graph!
A clever way to remember where variables go on a graph is to say
DRY MIX

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

• The best interval
would be to go by 5’s.

• 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
