Data

• What is data? Examples?– Information of observations (pennies)

• How is data valuable to scientists?

Data Tables

• What is a data table?– A way to organize data in columns so it is neat

and readable.• Where is the title?

Data Tables• What is a variable?

– Describes what is being collected in a data table.

• What is a unit? – Describes how the information was collected.

• Why is it important to have variables and units included on a data table?

Ordered Pairs

• What are ordered pairs?– Two pieces of data directly

corresponding to one another.(0,20) (2,23) (4,35)

(6,61) (8,71)(1,21) (3,27) (5,45)

(7,69)

What is the best way to identify an ordered pair? Pg.7

How are ordered pairs related to data tables?

Data Tables

• What does a complete data table have?

1. A descriptive title2. Variables describing WHAT

information has been collected3. Units telling HOW the variables were

measured4. Data collected in ordered pairs5. All work is NEAT and READABLE

C. Two pieces of data directly corresponding to one another.

D. A specialized vocabulary used to describe things in a specific field of study.

E. WHAT information is being collected

F. A brief way to describe the content of a book, graph, or data table.

G. HOW information was measuredGOOD LUCK! Done!

How to read a graph

• Title• Data• Variables• Units• Horizontal axis

– Bottom (X)

• Vertical axis– Side (Y)

How are data tables and graphs similar?

1. The same descriptive title2. The same variables and units3. The same data

How do you plot data on a graph?

• Intersection– Crossing of two data

lines

• Data point– Place where two data

lines cross

• Intervals– An even spacing of the

numbers along the axis of a graph

PRACTICE!

Y-axis

X-axis

Get Your Graph Paper!1. Draw your horizontal and vertical lines2. Look at the data and decide which variable is

the most consistent. It goes on the horizontal axis.

3. Number each axis in even intervals for the data you are graphing.

4. Plot your data from your data table onto your graph.

5. Put a title on your graph.

Multiple Line Graph

• A multiple line graph is used when comparing several different experiments utilizing similar data.
