Graphs
A way of representing information so the information can be
compared.
![Page 2: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/2.jpg)
Graphs are usually used for comparison, but they
can be used to make predictions.
![Page 3: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/3.jpg)
Graphs are also a way of organizing information
and recording information, but that is
not the main purpose of graphs.
![Page 4: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/4.jpg)
Required Parts of a Graph
• X axis
• Yaxis
![Page 5: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/5.jpg)
When making a graph, most people place the X axis on the bottom and the Y axis along the left
side. However, not every graph has to be that way.
![Page 6: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/6.jpg)
Some graphs place the X axis on top or the Y axis
on the right side. Sometimes there is more than one Y axis or X axis.
Do not let this confuse you. You read the graph
the same way.

Needed Parts of a Graph
• Title
• Labels
• Scale
![Page 8: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/8.jpg)
TitleA title informs the reader
of the graph what the graph is showing.
Sometimes you cannot tell by just looking at the
graph.
![Page 9: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/9.jpg)
LabelsLabels shows what each
part of the graph represents. Very important to label the X axis and Y axis. Other labels are up
to the maker. Keep it neat.
![Page 10: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/10.jpg)
ScaleSomething divided into
regular spaces for measuring.
![Page 11: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/11.jpg)
Very important when using a scale to keep the
numbers regularly spaced. You can go 5, 10, 15, 20 or 1, 2, 3, 4 or 2, 4, 6, 8 or 20, 30, 40, 50. Do
not just write the numbers you have, for
example 22, 37, 45, 77, 93.
![Page 12: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/12.jpg)
Some people say that when making a graph, you have to start the scale with 0. You do not. There also a way to shorten a scale when numbers are really
far apart.

TablesWay of organizing
information.
![Page 21: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/21.jpg)
Parts of a Table• Title
• Rows
• Columns
![Page 22: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/22.jpg)
In order to make a table, you must be able to
arrange the information into rows and columns so
they intersect.
![Page 23: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/23.jpg)
You can not make a table out of any information.
They must be related close enough to form intersecting rows and
columns.
![Page 24: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/24.jpg)
Most of the time, the rows and columns have labels to identify what you are
looking at. However, they do not have to have
labels.
![Page 25: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/25.jpg)
Concept MapA way of organizing
information that is not closely related
![Page 26: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/26.jpg)
Concept maps are read like a road map. Your follow the lines to the
next point. Just like you follow a road to a specific
point.
![Page 27: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/27.jpg)
As long as the points are connected by a line, then the information is related.
If the points are not connected by a line, then
the information is not related.
![Page 28: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/28.jpg)
To see how information is described, follow the
lines to the next point. The next point is a subcategory of the
previous point.
![Page 29: Graphs A way of representing information so the information can be compared](https://reader036.vdocuments.mx/reader036/viewer/2022062718/56649e895503460f94b8dc69/html5/thumbnails/29.jpg)
The next point is part of the previous point,
however the previous point is not part of the
next point.

Best Fit Line
A line used in a graph to determine the average of the data. The slope of the
line is used to find information. Also known as
linear fit.
