Handout Information on Graphing

Graph paper should be used unless done by computer and a grid should be overlaid at that time. Holes present should be on the left side or top of the graph. If stapled, it should be in the upper left corner.

Read from the bottom or right side of packet if attached to other sheets.

The graph title is displayed.

Axis and units are labeled with both quantity graphed and units of measure.

Unit divisions are appropriate and consistent with data to full axis.

All points plotted as instructed.

Smooth curve or straight lines are inserted via hand or computer to match the data behavior. Equations and regression values are desirable describing the data. Do not "connect the dots".

Proper format is observed. Numbers consistently increase from left to right or bottom to top.

Proper scale is used. Curves must be at least half the page in both length and width. Hint - Choose a convenient value just below the lowest data value and increment consistently to a value just above the largest data. Mark these regular intervals on the axis to fill it.

Graph using decimals for values less than 1. Do not use fractions.

Marked divisions should be "round" values that are legible and line up with the marks on the graph. Do not mark the graph with the values of the data.
