on the scale,
THEN ___________
to the the next
smallest decimal
place (next 1/10).

8. Graphing Data:
The data from physical science labs is frequently graphed for two reasons:
To ______________the data to others
To ___________the data (look for trends).

9. Physical Science: Chapter 1 Graphing
Graphing Data: Line Graphs
_____graphs are
used when data
is recorded for
_____________
changes in the
______________variable.

10. Physical Science: Chapter 1 Graphing
Graphing Data: Line Graphs
The _____________variable data is on the
_______(along
the bottom)
What is the
independent
variable on this
graph?

11. Physical Science: Chapter 1 Graphing
Graphing Data: Line Graphs
The _____________variable data is on the ______
( left side)
What is the
dependent
variable on this
graph?

12. Physical Science: Chapter 1 Graphing
Graphing Data: Line Graphs
If there is a mathematical
relationship between the dependent variable and
the independent variable
it can often be seen as the
__________________________.

13. Physical Science: Chapter 1 Graphing
Graphing Data: Line Graphs
Slope = rise/run
Rise = distance “up”
Slope = Δy / Δx
= y2 – y1
x2 – x1
Run = distance“across”

14. Physical Science: Chapter 1 Graphing
Does there appear to be a mathematical
relationship between Water temperature
and Heating
Time?_____
Calculate
the slope.

15. Physical Science: Chapter 1 Graphing
Creating Line Graphs
1). Label the independent variable,
including the SI units and axis values.
2). Label the dependent variable,
3). Label (title) the graph
4). Plot independent variable on x-axis.
5). Plot dependent variable on y-axis.
These two plots will form a point of
data.

16. Physical Science: Chapter 1 Graphing
Graphing Data:
_______graphs are used to _________data from _____________ things.

17. Physical Science: Chapter 1 Graphing
Creating Bar Graphs
1). Label the different TYPES of things being
graphed (along the bottom for vertical bar
graphs)
2). Label the units of measurement (along the
left side for vertical bar graphs).
3). Plot the height of the bar (for vertical bar
graphs) for each thing being graphed.
4). Label (title) the graph

18. Physical Science: Chapter 1 Graphing
Graphing Data:
________charts are used to show ___________
(what _________)
something is as _____of _______ category.

19. Physical Science: Chapter 1 Graphing
Creating Pie Charts
1). Draw a circle and divide the circle into
pieces representing the percentage of each
of the pieces.
2). Use a different color or shading for each
piece of the pie chart.
3). Label each piece (or have a color coded
chart)
4). Include exact percentages if possible.
5). Label the graph
