Bar or Line? One of the first things one needs to do when graphing is decide whether to make a bar graph or a line graph.

Bar Graphs are used for comparing This bar graph compares the unemployment rates for people with different levels of education.

Line graphs are used for showing trends This graph shows that the trend is that sales are increasing each year.

Line graphs also show relationships This graph shows the relationship between elevation and temperature. The higher the elevation, the lower the temperature.

Remember TAILS DRY MIX In order to make good graphs, all you have to remember is TIALS, DRY, and MIX

TAILS T is for Title

Point out the title People forget titles about 1/2 the time

TAILS A is for Axis We’ll talk more about the axis later

The Y axis goes up and down The X axis goes side to side

TAILS I is for Interval

Interval means make sure that each line is always worth the same amount… Like here they went by 5’s

TAILS L is for Label People forget to label their axis about 1/3 of the time

S is for Scale TAILS Make your graph big enough to be easily read. Use the whole paper or space instead of putting a tiny graph over in one corner

Remember that A was for Axis??? When figuring out what goes on which axis remember: DRY MIX

DRY DRY means that the: D ependent or R esponding variable belongs on the Y -axis

The percent depends on the quarter so the percent is the dependent or responding variable and belongs on the Y axis

MIX MIX means that the: M anipulated or I ndependent variable belongs on the X -axis

The Quarter is what we’re changing or manipulating so it is the independent variable and belongs on the X axis Review TAILS DRY and MIX
