TAILS
TT – Title
Choose a descriptive title that explains what is being measured in the graph

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.

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.

LABEL your axis
or data points
Singers
Give the axis a general label. What do those words mean?
Num

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

Motion Graph # 1Straight, Flat Line
• As time passes, there is no change in distance; no motion
4251
0011 0010 1010 1101 0001 0100 1011
Motion Graph # 2Straight, Increasing Line
• As time passes, distance increases
• The change in distance is constant – no stopping & starting
4251
0011 0010 1010 1101 0001 0100 1011
Motion Graph # 3Straight, Decreasing Line
• As time passes, distance decreases
• The change in distance is constant
4251
0011 0010 1010 1101 0001 0100 1011
Motion Graph # 4Changing Line
• A changing line means changing distance
• Distance increases doesn’t change distance decreases

Graphing acceleration
• Acceleration is always shown as a curved line
