How to graph data

The example below shows the changes in the temperature over a week in January.

The title of the graph is “Average Daily Temperature for January 1-7 in degrees Fahrenheit”.

To the left is a table that shows the date in one column and the corresponding temperature in the second column. The line graph on the right shows the degrees of temperature going up the vertical axis (up and down numbers on the left of the graph) and the days of the week on the horizontal axis (going sideways from left to right).

The points for the temperature for each day are connected by a line – thus the graph is a line graph.

Date     Temperature oF
1           10
2           25
3           30
4           42
5           23
6           25
7           40

Learning Standards

Mathematics Curriculum Framework, through grade 8.

Construct and use tables and graphs to interpret data sets.

8.EE Understand the connections between proportional relationships, lines, and linear equations.

8.F.5 Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally.

Massachusetts Science and Engineering Practices Progression Matrix

Describe, measure, estimate, and/or graph quantities such as area, volume, weight, and time to address scientific and engineering questions and problems.

Benchmarks: American Association for the Advancement of Science

The scale chosen for a graph or drawing makes a big difference in how useful it is. 9C/M6

Spreading data out on a number line helps to see what the extremes are, where they pile up, and where the gaps are. 9D/E4a

Often the best way to tell which kinds of change are happening is to make a table or graph of measurements. 11C/E2b

Tables, graphs, and symbols are alternative ways of representing data and relationships that can be translated from one to another. 9B/H4

Use numerical data in describing and comparing objects and events. 12D/E3

Read simple tables and graphs produced by others and describe what the tables and graphs show. 12D/E4**

Organize information in simple tables and graphs and identify relationships they reveal. 12D/M1

Understand oral, written, or visual presentations that incorporate circle charts, bar and line graphs, two-way data tables, diagrams, and symbols. 12D/M4*

Check graphs to see that they do not misrepresent results by using inappropriate scales or by failing to specify the axes clearly. 12E/H2
