• A visual representation of a relationship between, but not restricted to, two variables.
• Commonly consists of two axes called the x-axis (horizontal) and y-axis (vertical).

Line Graph • Scale line graph:
represents frequency distributions over time
• Y-axis represents frequency.
• X-axis represents time.
![Page 28: Tabular and Graphical Presentation of Data](https://reader035.fdocuments.us/reader035/viewer/2022062316/58f20ffc1a28ab60238b45c9/html5/thumbnails/28.jpg)
Figure 8.1. Trends of Dropout Students in Public Schools in Philippines from Year 1991 to 2000.
Y-axis should beshorter than X-axis
Start the Y-axis with zero
Select an interval size
Example
![Page 29: Tabular and Graphical Presentation of Data](https://reader035.fdocuments.us/reader035/viewer/2022062316/58f20ffc1a28ab60238b45c9/html5/thumbnails/29.jpg)
Bar Graph • Uses differently
coloured or patterned bars to represent different classes.
• Y-axis represents frequency.
• X-axis may represent time or different classes.
![Page 30: Tabular and Graphical Presentation of Data](https://reader035.fdocuments.us/reader035/viewer/2022062316/58f20ffc1a28ab60238b45c9/html5/thumbnails/30.jpg)
Make bars the same width
Arrange categories that define bars ina natural order
Length of bars should beproportional to the frequency of event
Example
![Page 31: Tabular and Graphical Presentation of Data](https://reader035.fdocuments.us/reader035/viewer/2022062316/58f20ffc1a28ab60238b45c9/html5/thumbnails/31.jpg)
Clustered Bar Graph • Bars can be
presented as clusters of sub-groups in clustered bar charts.
• These are useful to compare values across categories.
• They are sometimes called stacked bar charts.
![Page 32: Tabular and Graphical Presentation of Data](https://reader035.fdocuments.us/reader035/viewer/2022062316/58f20ffc1a28ab60238b45c9/html5/thumbnails/32.jpg)
Show no more than three sub-bars within a group of bars.
Leave a space between adjacent groups of bars.
Example
Use different colours or patterns to show different sub-groups for the variables being shown.
Include a legend that interprets the different colours and patterns.
![Page 33: Tabular and Graphical Presentation of Data](https://reader035.fdocuments.us/reader035/viewer/2022062316/58f20ffc1a28ab60238b45c9/html5/thumbnails/33.jpg)
Histograms • A representation of
a frequency distribution by means of rectangles
Width of bars represents class intervals
Height represents corresponding frequency

Pie Chart• A circular (360 degree)
graphic representation• Compares subclasses
or categories to the whole class or category using differently coloured or patterned segments

Scatter Plot• A scatter plot is a two- or
three-dimensional plot that shows the joint variation of two (or three) variables from a group of observations.
• The coordinates of each point in the plot correspond to the data values for a single observation.

Pictographs• Diagrams that show and
compare data by using picture symbols.
• Each of these symbols corresponds to a specific quantity and is repeated a number of times.
