Displaying Data: Graphs

ObjectiveStudents will be able to

collect, record, organize, and display data using frequency tables, single bar graphs, or

single line graphs.

ObjectiveStudents will be able to formulate and answer

questions by interpreting and analyzing displays of data, including frequency tables,

single bar graphs, or single line graphs.

Sometimes, it is easier to understand data if it

is organized and displayed.You

can organize data

by:

Frequency Table Line Graph Bar Graph Pie Chart Pictograph

Frequency Table

• Shows the number of times something occurs.

• This shows how many times a number on a dice was rolled.

Bar Graphs

• Bar graphs are another way to show data.

• Double bar graphs help you to compare data. 0

Line Graphs

Line graphs are good for showing changes in data over time when working with dates.

Double line graphs can help you show even more data and compare data.

Pictographs• Pictographs are often

used to show data in newspapers and magazines because they get your attention.

• Each picture represents a specific number of data.

Pie Charts/Graphs

• Circle or pie charts are another way to show data, and compare data to percentages or fractions of a whole.

Frequency Table: Activities How did you do? Does your table look the same?

How did you do imputing the data? Does the data match?

We Do

One dice per pair, one frequency chart per student

Dice is rolled not thrown, bounced, etc…. Students take turn rolling the dice. All students write down the information.In partners, roll the dice 30 times. For each roll mark down which number the dice landed on. When you are finished, count up the tallies and write the number in the correct column. Save this data for tomorrow’s activity. Don’t forget to label your table and give it a title.

Bar Graphs

Bar Graphs display data so that it can be easily understood. You can use

graphs to compare sets of data.

Bar Graphs How to make a bar graph:1. Use the data from the table to choose the right scale.  All scales start at 0.

2. Draw and label the scale on the vertical axis.

3. Draw and label the horizontal axis.

4. List the name of each item.

5. Draw vertical bars to represent each number.

6. Title the graph.

Line Graphs

Line GraphsA line graph uses points and lines on a grid to show change over a period of time.

Line GraphsHow to make a line graph:1. Use the data from the table to choose an appropriate scale. All scales start at 0.

2. Draw and label the scale on the vertical axis. 

  3. Draw and label the horizontal axis. 

4. List the name of each item.

5. Locate the points on the graph.

6. Connect the points with line segments.

7. Write the title of the line graph.

Line GraphsWhat grade did Frank get on the third test?

First find test number 3 on the horizontal axis.

Then move up until you hit the point.

You see that Frank got a 100 on the third test.
